In this lesson, we will learn how to describe the use of a commutator in converting the output of an alternating current generator into a direct current.

Lesson Plan

Students will be able to

describe how the connections of the ends of a uniformly rotating conducting coil must connect to commutator rings to produce induced current in an external circuit that varies in magnitude but not in direction,
compare the changes in orientation of a uniformly rotating conducting coil, with terminals connected to commutator rings, to graphs of change of induced current in an external circuit with time.
