Electrical Help at Your Fingertips

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..

The first step in knowing how to fix a broken light switch is being able to identify when one exists. There are a few telltale signs that a light switch may be broken, which include:
-The switch does not click when engaged.
-The switch feels loose or wobbly.

Unlike an asynchronous AC motor, a synchronous AC motor rotates at the same speed as the frequency of the AC power supply. In order to achieve this, the synchronous AC motor must be synchronized with the power supply using a feedback system. Read more..

Direct current (DC) is an electric current that flows in one direction only. DC is the kind of current produced by batteries, fuel cells, and solar panels. Read more..
