What is a rectifier?
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. Read more..
What is an AC motor?
An AC motor is an electric motor that uses alternating current (AC) instead of direct current (DC). AC motors are more efficient than DC motors and can be found in a variety of applications, including fans, pumps, and compressors. Read more..
What is alternating current?
Alternating current (AC) is an electric current that reverses direction periodically. This means that the voltage of an AC signal also reverses direction periodically.
The frequency of an AC signal is the number of times per second that the current or voltage reverses direction. Read more..
