Electrical Help at Your Fingertips

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..

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. In other words, the higher the voltage, the higher the current. Read more..

An alternator is a device that creates alternating current by transforming mechanical energy into electrical energy. 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..
