Electric Generators

• The basic idea behind most modern power plants is to convert mechanical energy into electricity by rotating coils of wire in a strong magnetic field.
• A coil of wire rotating with uniform angular speed leads to a magnetic flux which changes sinusoidally with time. That, in turn, leads to an induced voltage which also varies sinusoidally.
• So simple electric generators produce AC (Alternating Current) electricity.
