GENERATOR HAND PAIR + LAMPUNIT

These two generators can be connected together to show motor/generator effect, where one student generates electricity by turning the handle, and the other unit held by another student becomes a motor, with it's handle rotating because of the resulting current. Reversal of the turning causes reverse handle turning on the other unit. The unit can dramatically demonstrate resistance load when attached to the lamp unit and each lamp is screwed in as a student steadily turns the handle, feeling the load increase as each lamp is added to the circuit.
