Alternating current is any current that reverses direction repeatedly ; almost always this takes the form of a sine wave.

Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time.

Alternating current is normally preferred as its voltage may be easily stepped up by a transformer in order to minimize resistive loss in the conductors used to transmit power over great distances ; another set of transformers is required to step it back down to safer or more usable voltage levels at destination.

TRIAC, from Triode for Alternating Current, is a genericized tradename for an electronic component that can conduct current in either direction when it is triggered ( turned on ), and is formally called a bidirectional triode thyristor or bilateral triode thyristor.

The SIDAC, or Silicon Diode for Alternating Current, is another member of the thyristor family.

Also referred to as a SYDAC ( Silicon thYristor for Alternating Current ), bi-directional thyristor breakover diode, or more simply a bi-directional thyristor diode, it is technically specified as a bilateral voltage triggered switch.

* Alternating current ( AC ) is commonly used to detect surface discontinuities.

Alternating current and pulsed current is also possible but rarely used.
