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.

What measures electricity?
If this question is asking about the box supplied by your utility company which counts the kilowatt.hours you used, so they can send you a bill for electricity, it is called an electricity meter. If you are asking about the name of the standard unit used to measure a quantity of electricity used, it is called the kilowatt.hour (or k.Wh for short.)
When did Victorians first use electricity?
the Victorians didn't use electricity but the light bulb did and it was the only thing that did. electricity
What is the importance in the discovery of electricity?
That you were able to ask this question. Without electricity, we wouldn't have many of the things we have now. A LOT of stuff use electricity to work.
Where did Thomas Edison invented electricity?
Thomas Edison did not invent electricity. He invented means of making use of electricity.
How do electricity generating boards measure electricity?
.
How you test the electric motor that it produces electricity?
Electric motors do not produce electricity, they use electricity, and convert that energy to another form of energy, that we measure in horsepower. See related links.
What kind of unit of electricty do american use Watts or volts?
American use both watts and volts to measure units of electricity.

What Instrument measures electricity usage?
To measure electricity you use a multimeter to display voltage, resistance, amperage, etc. But to measure the rate at which you use electricity, I would recommend a Kill-A-Watt device, which tells you how much electricity appliances in your home are using, among other useful information.AnswerWhen you say 'electricity usage', you presumably mean 'energy consumption'? If this is the case, then you measure energy consumption using an energy meter which expresses energy consumption in kilowatt hours.
