In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction. Most of the digital electronics that you build will use DC.
Synchronous and Induction Motors are two difference types of AC electric motors. AC electric motors are an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts: an outside stationary stator and an inside rotor. Synchronous motors and induction motors are the most widely used types of AC motor.
