This is a great way to show the mechanical equivalent of electrical energy. Try cranking without the light bulb in place....you will feel very little resistance. Then screw in the light bulb. It is definitely harder to crank. Students can actually feel the mechanical energy that is being transformed into electricity.

Oh! That's How it Works!

I teach fourth and fifth graders and they used this constantly during our electricity work. They ran it fast for a bright light, slowly for a dim one. They attached it to a buzzer to see how fast they had to crank it to create 3 volts. They loved that it had the same motor in it that we were using in other experiments so they could see how a generator is the inverse of a motor. Very cool.

This hand held generator is an ideal way to demonstrate the transformation of mechanical energy into electrical energy. This unit produces a terminal voltage or 6V and maximum current output or 0.2A. Comes with two 15 inch leads for powering your other electric circuits, and with a standard light-bulb. Great for school science projects or classroom demonstration.
Features:
- Demonstrates mechanical-electrical energy transformation
- Voltage of 6V
- Max current output 1.2A
- Two 15in. leads
- Standard light bulb
