Electric Generator

We know that the motors get their power from the batteries that are inside the RCX. The motor converts electrical power into rotational motion.

But, is it possible to go the other way. Can you create electrical power from rotational motion?

YES! Try the following experiment. Connect two motors together with a motor cable as shown. Attach wheels to the axles so you can turn it. Turn one of the wheels. Does the other one turn?

The motor has become an electric generator. Rotational motion (supplied by you) is converted into electrical power, which is sent to the other motor.

Research idea: Have your students write a report on how real electric generators work and what fuels they use to create electricity.
