Ammeters are always connected in series with the circuit to be tested. It is obtained by multiplying the current in amperes by the time in hours during which current flows. For example, a battery which provides 5 amperes for 20 hours is said to deliver ampere - hours. One ampere is equal to a current flow of one coulomb per second. Apparent power is the product of the rms voltage and the rms current. It is made up of conductors which rotate through a magnetic field to provide voltage or force by electromagnetic induction.

Understanding electricity requires knowledge of these basic electrical terms. Alternating Current (AC) — An electric current that reverses its direction many times a second at regular intervals. One ampere is equal to a current flow of one coulomb per second. Apparent Power — Measured in volt-ampers (VA).

AC — Alternating Current. The abbreviations AC and DC are often used to mean simply alternating and direct , as when they modify current or voltage. AC is the form in which electric power is delivered to businesses and residences. If you think in terms of water through a hose, amperage would be a measure of water volume flowing through the hose. Lower gauge numbers indicate larger conductor size.

Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt , one joule per second. Electric power is usually produced by electric generators , but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes as domestic mains electricity by the electric power industry through an electric power grid.
