Electrical Help at Your Fingertips

An AC motor works by using electromagnetism to convert electrical energy into mechanical energy. The alternating current creates a rotating magnetic field that interacts with the armature, or rotor, of the motor to create torque. 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..

Ohm’s law is used in many branches of physics, including electricity, magnetism, and optics. It can be used to design electrical circuits, calculate power dissipation in electronic devices, and troubleshoot electrical problems. Read more.

generators transform mechanical energy into electrical energy. The mechanism involved is similar to that of an alternator.. Read more..
