Can electricity travel through air?
Yes. It can (and does) travel in the form of lightning. Static electricity that zaps us when we touch something grounded on a very dry day is the same thing, only on a smaller scale. Electricity would rather not travel through air, but when charges build and the difference of potential gets high enough, that electrostatic potential will ionize air and the charge will jump from one place to another following the ionized trail and further ionizing the air.

copper in wires is a metal, and like all metals it is made up of atoms bound together. Basically, atoms are made of a nucleus in the middle, and electrons revolving around the nucleas. In all elements except metals, the nucleus doesn't "let go" of the electrons (unless there is a chemical reaction, …but dont worry about that for now), but in metals, the electrons are"allowed to go around" to other nucleuses, electrons are allowed to flow around atoms freely in a metal. It is this flow of electrons that is electricity. however a driving force is needed to make the electrons flow around the copper wire, this comes from a battery or a dynamo. (MORE)
it travels because there are sound waves in the air and they vibrate in your ear.
yes. if light didn't travel through air, then you wouldn't be able to see anything!
yes, it's called lightning. also in the case of high voltages the general rule of clearance is 1 foot for every 1000 volts.. so those high tension towers you see can carry in excess of 13200 volts so if you get any closer than 14 feet the electricity could jump to you.
\nElectricity can travel throughout freely moving Electrons, like in metal which is in wires under the rubber.
yes. that is why you are able to see objects. light reflects off objects allowing you to see.
Pollen travels through the air by a wind blowing the pollen and landing on soil and re growing this is called pollenation
We are in air, and we can hear each other. Thus, sound can travel in air. Yes. A sound wave can travel through air (gases), liquids, and solids.
Electricity travels through power lines because the wires form acomplete loop. Power lines can be overhead or underground and ifone is broken, the electricity cannot flow through it.
Heat can travel in air by convection, but radiation (electromechanical wave motion) is the most efficient way to transfer heat (energy) through air.
Electricity only moves through the air if there are electrically charged particles in the air and a live current passed through it. It also travels in the form of static electricity (lightning).
Light travels as an electromagnetic wave radiation, along with other radiation like radio and TV waves, microwaves, UV, and so on. All these are basically the same but have different frequencies. Air does not absorb light much, it is almost transparent to light unless it contains dust etc, so there …is no reason why it should not travel through air. But don't confuse it with sound, sound is a compression wave in the air and is quite different to light in the way it travels. (MORE)
a force applied by a simple machine energy flowing through the water cycle Earth's gravitational pull on an object energy being transferred from place to place
Yes, but only if it is not pure water. Pure water, that is, H2O without any other substances, does not conduct electricity.
We are energy ourselves, different frequencies determine emotion happiness or sadness. The human body is 90% space, what seems concrete is only an illusion.
Metal is a conductor. What this means is that it has a very low resistance to electricity, allowing the electricity to flow through it. I suggest you learn how electricity works first to understand how electricity can flow through objects. http://millerwelds.com/education/basicelec/
Yes, electricity can travel through a vacuum. Older cathode ray televisions send a beam of electrons at high speed through a vacuum. When they hit the screen they excite a "phosphor" which glows, putting light onto the TV screen. In a vacuum you won't see a spark, as there is nothing there for… the charged particles to react with. Electricity moving along a wire is slowed down as it has to react slightly with all the atoms in the wire. Lightning ionises the atoms as it comes through the air, knocking the electrons out of their orbits and creating a spark. A vacuum has nothing to slow the speed of electricity. So a vacuum is actually the best conductor of electricity. (MORE)
Wood is a poor conductor. However lightning at high voltages can travel through wood. Normally wood is an insulator.
No, sperm use a small whip-like tail to travel through a liquid medium. Also not just any liquid medium, it must be rather viscous for optimal travel, like that found in semen. The tail would be useless in air.
If it was made from clean water electricity will have problems. The more impurities the better it conducts.
Yes it does by the movement of electrons primarily over the surface of the copper conductor.
Yes. If you can't get to the space behind the wall, you may be able to get the extension nozzle of spray foam can behind the outlet and seal it off. Ideally in new construction you would use spray foam on all wall penetrations like where electric wires pass through studs. There are gaskets availa…ble at DYI stores that can be used to stop air infiltration. These gaskets are installed between the cover plate and the receptacle or wall switch. The gaskets are only needed on outside walls. On new installations use a PVC junction box that is completely sealed. There is a neoprene strip that covers the entry points where the conductors enter the box and are self sealing. On the front of the junction box there is a drywall strip that circles the front of the box. This also has a neoprene strip that seals the box when the drywall is installed up against the strip. The wall vapour barrier is also taped to this strip on the box to make a completely sealed system to prevent drafts entering through the house's outside walls. (MORE)
Sounds vibrate the air molecules, when the vibrating molecules reach your ear, you ear the sound, there are no molecules in space, thus no sound in space
No, the second best electrical insulator is dry air. The best is a vacuum. Moist air is more conductive than dry air, because of the ionic content in water droplets. A good insulator has very high resistance, which would require a very high voltage in order for a current to occur. Another considerat…ion is the length of the insulating bar (or the spacing between the two electrodes in a medium). The longer the spacing, the higher the total resistance. More than 1e6 V across a spacing of 1 m may be needed for a spark to occur in air (it is hard to say because it depends on the concentration of ions in air). Hence a static shock (discharge) will occur when your finger is almost touching the door knob after walking across a carpeted area when the air is dry, but not when your finger is an inch away from the door knob, for example.

It all depends on the type of magnet, and if the chemical formula shows that it has free electrons to carry the electricity.
A smell is transmitted through molecules in the air. These molecules can from the source to the nose through air currents, or through diffusion.\n
If you are talking about flying then its a process called lift. It was found that air pressure reduces at slower speeds and increases at higher speeds. Air planes fly because the wing of the plane channels and splits air. Some air moves over the top of the wing and some air moves under it. The wing …is curved on the top forcing the air to travel farther and slow down. Compared to the underside of a wing which is straight and allows the air to continue at the same speed it approaches the wing of the plane. Because the speed of the air is faster on the bottom of the wing the air pressure increases forcing the wing to rise up because the air is pushing up on the wing. (MORE)
Sound energy gets propagated through the material medium (air) in the form of waves. There are two kinds of waves. One is transverse. Good example is waves produced on the surface of water. The other is longitudinal. Sound waves are longitudinal in nature. Imagine a fork is kept erect on a stand. Le…t us make it vibrate. As the prong starts vibrating left and right way, sound waves traverse through air medium longitudinally. Let us picturize this using our imaginative power. Let us consider the air is divided into so many layers (vertical) one by the side of the other. As the prong goes to our right extreme, this would compress the layers and this compression would be handed over to the adjacent layers and so this disturbance continues to all the layers in the medium. Now, when the prong comes to our left extreme, then a kind vacuum will be created and so the layers will be pulled towards the prong. Thus, an expansion known as rarefaction takes place. This rarefaction information will be passed continuously to all the layers in the medium. So, when the prong does vibration continuously, the compressions and rarefactions pass through the medium repeatedly. This is known as propagation of sound waves through air medium. (MORE)
Electricity travels through a circut. A circut id domething that goes around, completeing a loop. Think of NASCAR. The cars are going around and around, doing laps around the track, which is a circut.
Yes. That is how you normally hear it. It moves at over 700 miles an hour.
Yes - That is how we hear sounds. Noise travels through the air as 'sound waves'.
Each day we breathe about 20,000 times. All of this breathing couldn't happen without help from the respiratory system, which includes the nose, throat, voice box, windpipe, and lungs. With each breath, you take in air through your nostrils and mouth, and your lungs fill up and empty out.
If the wrench is made of metal, which almost all are, the answer is yes.
This is sort of a complex answer, so I'll separate it into parts that at least make sense to me. The first answer is that given enough potential, anything will conduct electricity. There is a method of radioactive waste neutralization called volcanization that takes this principle to heart, in ess…ence you put a piece of radioactive waste in the ground between two strong electrodes and jam so much potential that it literally glasses the ground and the waste. The second answer applies to room temperature and common, mostly dry situations; only metals will conduct electricity. Dry salts and covalently bonded molecules, or other non-polar molecules will not conduct electricity. This has to do with metals electrical structure, they have this 'sea' of electrons that flow easily between metal atoms, whereas in ionic molecules electrons are stolen outright and the cyrstals are held together through electrostatic force, and in covalently bonded molecules the electrons are held in tight bonds between two atoms. The third answer applies to when things are wet; metals still conduct, that's almost always a given, but when aqueous(dissolved) salts will make ions, which are charged particles, and will conduct. This is why pure deionized water is non-conductive, but tap water is. Its because tap water has many different salts and charged species capable of conducting in it. Polar molecules will also conduct electricity, albeit weakly. TL;DR Metals always conduct, water will conduct when a salt is dissolved in it. (MORE)
The Oxygen fuels the reaction in a fire, oxygen is necessary for combustion. As the reaction takes place hydrocarbons are produced. These gas particles are produced from incomplete combustion of longer chains of hydrocarbons (wood). Heat rises, so do the gas particles as they continue to react (bu…rn). Combusion is considered complete when the hydrocarbon bonds are all broken producing water (hydrogen/oxygen) and carbon dioxide (carbon/oxygen). (MORE)
Yes. If they didn't you wouldn't hear sound. Your ear picks up the vibrations it receives and interprets them as sounds.
Although you cant see them,all over your house there is hundrends of wires passing through walls, and ceilings. The wires have metal in them and electricity passes through the metal and into all sorts of machines that need electricity to power them xx
The motion of a basketball follows the basic laws of physics as explained by Isaac Newton. When you throw a basketball you are causing it to move, and once it starts moving it will continue to move because of its momemtum; meanwhile it will simultaneously be falling, under the influence of gravity. …(Note that even if a basketball is moving upward, it is still under the influence of gravity, and its upward motion will gradually curve into a downward motion.) Forward momentum and gravity combine to produce the typical ballistic curve of a thrown object (whether a basketball or any other thrown object). Air resistance is also a factor, although it is relatively minor for basketballs, because they move at a relatively low speed. That's how a basketball travels through the air. (MORE)
Seeds travel through the air with wind. Flowers drop seeds and the air carries them.

1) If the voltage per meter is very high, the isolation of air may "break", and a strong current may flow. 2) There may be a current, without the movement of charges in part of a circuit, through an effect known as capacitance: charges that build up on one side of a vacuum, or air, may induce the …build-up of an opposite charge on the other side. If the current has a high frequency, such a capacitor will have a low impedance (this is similar to a resistance) to the current. (MORE)
Well, the neutron has a negative charge so really it doesn't affect this question at all.
well, if the neutron touches the negative charge it repels, so it doesn't really affect this question at all.
gold, that is why they use it for computer connections, also gold does not corrode
If the electricity is strong enough it can jump through the air. Google Jacob's ladder electricity for more.
Yes. When that happens over a short distance, we call it a " spark ". When it happens over a longer distance, we call it " lightning ".
20KV can throw a spark about a centimeter long in dry air. the distance at other voltages is directly proportional to the voltage. you should be able to calculate the distances for other voltages yourself from this info.
Yes but bananas are not used widely in electrical wiring becausethey tend to go rotten in a short time. Also the resistance is morethan copper wire.
Sound waves would be the commonest method of transferringinformation through air. This transfer relies on thecompression/rarefaction of the density of the air. Electromagnetic waves travel though space without needing anyintervening air at all. This is the manner in which the light andheat from the …Sun reach us - both electromagnetic waves. Theoretically, gravity waves may also reach us through space, andwe certainly feel the effect of the other planets in our Solarsystem. (MORE)
Anything through which electricity travels easily is called a conductor . That includes metals, a solution with ions, and several other substances.
