What is three phase supply , rectifiers , current , voltage , timers , controllers etc

Question

Accepted Answer

Three phase supply is a type of electrical power transmission that uses three alternating currents.

Three phase supply consists of three alternating currents that are 120 degrees out of phase with each other.
Rectifiers are electronic devices used to convert alternating current (AC) to direct current (DC).
Current is the flow of electric charge in a circuit, measured in amperes (A).
Voltage is the electric potential difference between two points in a circuit, measured in volts (V).
Timers are devices used to control the timing of electrical circuits or processes.
Controllers are devices used to regulate or control the operation of electrical systems or processes.
