AC Power - Wikipedia
Power in an electric circuit is the rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow.. The portion of power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as ... Read Article

Ammeter - Wikipedia
An ammeter (from Ampere Meter) is a measuring instrument used to measure the current in a circuit.Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.Early ammeters were laboratory instruments which relied on the Earth's magnetic field for operation. ...
