The War of Currents ended with alternating current (AC) as the only means of long distance power transmission.

An induction heater (for any process) consists of an electromagnet, through which a high-frequency alternating current (AC) is passed.

The overhead line voltage is 25 kilo-volt (kV) alternating current (AC) as is standard in many countries.

Impedance is the opposition to the flow of alternating current (AC) in a complex system.

Rectification is the process of converting alternating current (AC) to direct current (DC).

These transform current from the National grid at 6,600 volts AC.

The exciter coil is pumped with an AC current and emits a magnetic field.

Utility frequency, frequency of the alternating current (AC) in an electric power grid.

Transformer or Current clamp meter, (suitable for AC current only).

Rogowski coil, electrical device for measuring alternating current (AC) or high speed current pulses.
