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..

AFCIs work by sensing when an arc fault is about to occur and then interrupting the flow of electricity before the arc can form. 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..

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..
