# What is the unit used to measure electricity?

-- volt -- ampere -- coulomb -- watt -- watt-second Alternative answer 'Electricity' is not a quantity, so has no unit of measurement. So, what you are probably referring to is ' energy '. The SI unit of energy is the joule ( J ). An alternative unit, used by electricity util…ity companies for the purpose of billing its consumers, is the kilowatt hour ( kW . h ). However, the questioner might also be referring to an alternative unit of measurement for energy, the ' unit ', which is short for 'Board of Trade Unit' which, in the UK, is the equivalent of a kilowatt hour , and used for billing consumers (e.g. an electricity bill might be based on a price of '15 pence per unit'). So, 1 unit = 1 kW . h Other 'electrical' units include: .
the unit of electrical current (I) is the ampere .
the unit of electrical charge (Q) is the coulomb .
the unit of potential difference (V) is the volt .
the unit of resistance (R) is the ohm Another unit is a joule, it's the determination of the mechanical equivalent of heat and the joule-thompson effect. This effect is the conversion of mechanical, electrical or magnetic energy into heat. (MORE)

# How do you measure an electrical current?

In an electrical circuit there is a flow of electrons. The flow is induced by the creation at a production station, battery, or other supply of an "Electromotive Force (E)". The size of the electromotive force is measured in "Volts"..
The rate of flow of the electrons through the circuit is called… the "Current (I)". Current is measured in "Amperes"..
The typical conductor for transporting electrons through a circuit is wire and the smaller the diameter of the wire the more the "Resistance(R)" to the flow; the larger the diameter, the less the resistance. Resistance is measured in OHMS..
Definitions of volt, ampere, and ohm: .
1 volt : Electromotive force required to send a current of 1 ampere through a system in which the resistance measures 1 ohm..
1 ampere : Rate of flow of electrons in a system in which the electromotive force is 1 volt and the resistance, 1 ohm..
1 ohm : Resistance offered by a system in which the electromotive force is 1 volt and the current, 1 ampere..

# Using a cathode ray oscilloscope how do you measure the current in an electric circuit?

Cathode ray oscilloscope(CRO) is a device used to see the voltage across a particular element of your circuit and the wave form can also be seen on CRO. But you actually cannot measure the current using CRO as it is meant to give the voltage levels across any element in eletrically enegized circuit.… however Digital Multimeter can do this job. But while using DMM to measure current one thing should be kept in mind that your circuit should be linear so that if you break the circuit to find current in series the current could not change in circuit.

# What is the normal current when used electric current for direct current?

It doesn't make any sense, but I'd say 12 v? === Most electronics use direct current. Direct current is what you get from a battery. The electricity that is delivered to your house and accessed via wall sockets is alternating current. It is called alternating current because unlike direct …current which flows directly in one direction, alternating current alternates directions at a frequency of 60 times per second in the U. S. and 50 times a second in Europe. Most electric motors use alternating current. Electronic devices and chargers have a box, usually built into the plug or sometimes along the power cord, that contains a device to change the alternating current to direct current. ===== The reason alternating current is delivered to houses is: The loss of energy in the cables and wires that carry electricity is less when it's transported at higher voltage. So the electric companies move it around the country, between cities, and from the power generating plants to your neighborhood, at very high voltages, and then step it down just before it enters the houses on the block. To change voltage up and down at various points in the process, transformers are used, and transformers only work with alternating current. (MORE)
