If you don't know the answer to this question than you shouldn't be using a mutimeter. Get some electrical/electronic training first then read the instruction manual for your meter. If you try to do this the wrong way, you could be injured or killed!!!
Electric current is measured using an instrument called an ammeter . The SI unit of measurement for current is the ampere , which is defined in terms of the force between parallel, current-carrying, conductors due to the interaction of their magnetic fields.
The instrument that is used in measuring current is called anammeter. While, ampere is the unit used to get the amount ofcurrent.
-- 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)

The instrument used to measure electrical current is called an ammeter , which is actually a shortened form of 'ampmeter'. The current is measured in amperes. In scientific labs, amuch more sensitive instrument called a galvanometer isused to measure very small currents.
It is mostly convention. However this produces conflicts with theconventional mathematics usage of i as the square root of -1 incomplex numbers, so in electronics the convention is to use j asthe square root of -1 instead when working with complex numbers inthe analysis of AC circuits.
The SI Base Unit of electric current is the ampere (symbol: A ), which is defined in terms of its magnetic effect, as follows: 'that constant current which, when maintained in two straight, parallel, conductors of infinite length and negligible circular cross-sectional area, and placed one met…re apart in a vacuum, would produce between them a force equal to 2 x 10 -7 newton per metre of length.'

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..

amps Answer Electric current is measured by means of an ammeter . Electric current is expressed in amperes (symbol: A ), which is defined in terms of the magnetic effect of an electric current -i.e. the force between two, parallel, current-carrying conductors.
The light bulb creates light when electric current flows through the filament. Electric current is the movement of charges. It takes electric current to run an electric motor.
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
We measure electric current in charges per unit time past a given point. This is amperes , or just amps . Use the link below for more information.
Current is a simple descriptor, I was taught to always use it in school as leaving it off was an error. For instance you cannot say A for AC (Alternating Current) as A is amperage.
The unit used to measure quantities of electrical current flow is called the ampere , which is equivalent to one coulomb of electrical charge flowing during one second of time.
An ammeter either directly, or via a current transformer, is used to measure current in a circuit. Current transformers (CTs) are necessary when either (1) you need to measure the large currents flowing in high-voltage systems (a CT will isolate the HV system from the ammeter to which it is …connected, as well as reduce the value of the HV current) or (2) you need to reduce the very large currents to be measured in medium-voltage systems.

The easiest way to answer your question is to point out that every device you own or use, which you plug into the wall or which contains a battery, makes available to you some use of electrical current. Whatever you use each of those devices for is a use of current electricity.
In the so-called "International System of Units", which are based on metric units, and which form the basis for the electrical units we use, both work and energy have the same unit, called the "Joule". Or to make it more simple. In particular, for electrical power we use the "Watt" (name…d after the scientist James Watt): 1 Watt = 1 Joule / Second. ===== Very nice.

Most multimeters can be used for measuring current and if t is aclamp multimetre it can also be used for reading amperage Comment "Amperage" is current!
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.

Electricity has been found to be the best thing to use for an electric current.
The current is the amperage. It is measured in series. Voltage is measured across the line (parallel).
An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.
Electrical current is measured in Amperes which is abbreviated toamps. When dealing with formulae the letter I is used to representcurrent, for example: Power = Voltage Ã Current = volts Ã amps = V Ã I Small currents in electrical engineering use the lower case i; thiscan cause confusion… with the lower case i that mathematicians usefor â-1, so they use j for â-1 instead.

Electric current is the time rate of change of the scalar charge, thus it is a scalar quantity. The scalar derivative of a scalar value is a scalar value.
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)
Amperes or amps measures the electrical current. Think of it as a flow of water through a hose to simplify.
Here are a few examples... - The electrical current is monitored. - The current of electricity is measured in volts. - The electrical current of telephone wiring is 82 volts. They may not be worded the same, but they have the same initial meaning.
an ameter is used to measure an electric current an glory likes Matt marsh :0
to measure current, place the ammeter in the path of the current flow so that the electrons must flow through the ammeter. make sure the power is on. polarity is critical.
Power is basically the voltage times the amps where more of either is more power.
