They transform mechanical energy into electricity. Generators that produce direct current are called dynamos, and those that produce alternating current are called alternators.
-Dynamo: consists of a magnet and a rotary coil, that have, at the end, two semi-circular conductors, wich form the commutator.
-Alternator: is almost identical to a dynamo, except for the commutator, wich consists of two metallic rings connected to carbón brushes.
2.Electric motors
Is a device that can transform electrical energy into movement.
3.Relays
Is an electromagnetic component that works as a switch. When electricity passes through the coil, it acts like a magnet.
