And also what is the difference between AC DC motorsNot just car motors.
AC and DC motors work differently -- For DC motors, there is a permanent magnet and a bunch of copper wiring around it. When you put electricity through the wire, it induces an electromagnetic current, which repels the permanent magnet and causes it to spin. AC motors do this using an alternating current, while DC motors use direct current. AC is like a sin wave -- the voltage varies between -120V and +120V in a sine wave (usually 60Hz frequency in US I believe) DC current is a constant current (usually less -- 12V or so)
