Alternating Current (AC)

Definition - What does Alternating Current (AC) mean?

An Alternating Current is a form of electric current that flows in a rotating direction. Abbreviated as AC, this current flow is a preferred form of electric power that is commonly used in residential and commercial organizations. The waveform of an Alternating Current is usually a sine wave. This current is used to transmit information through amplitude modulation. It is also used in other various applications such as radio signals and audio signals.

Petropedia explains Alternating Current (AC)

Alternating Current motors and field measurement are basic operations in the oil and gas industry. Unlike a direct current, Alternating Current flows in sine wave form in alternate directions. This current form is used to transmit signals to the different processing units offshore. Because an AC can carry encoded information, it is easy to transmit signals to the remote machinery. When a higher voltage is used, the Alternating Current is transmitted efficiently. In the petroleum industry, Alternating Current motors are commonly used in pumps, fans and other devices.
