Generation of Alternating Current

In this interactive resource adapted from the Wisconsin Online Resource Center, learn how a generator produces alternating current. More specifically, see how slip rings, brushes, an armature loop, and a magnetic field interact to produce single-phase alternating current. Animations show how positive and negative voltages are induced into the armature loop as it rotates through the magnetic field, and how the polarity of the voltage changes periodically, visualized as a sine wave.

This media asset was adapted from "Generation of Alternating Current" by WISCONLINE.
