AC power

In an electric circuit, instantaneous power is the time rate of flow of energy past a given point of the circuit.

Alternating current

Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Maximum power transfer theorem and Alternating current are electrical engineering.

Antenna (radio)

In radio engineering, an antenna (American English) or aerial (British English) is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.
