Explores the practical
applications of:
* Electric motors through assemblies of a flexible coupling,
friction drive, and a friction-drive car.
* Electrical generators through the assembly of a motor-
generator coupled set.
The motor is fed with battery current and the generator lights up
the bulb. Two motors are used to perform a total of 4
experiments. The functions and applications of both motors and
generators are explained in the summaries.
Uses two "D" batteries.
Note: Batteries are not provided with the kits
