Elements of electrical circuits

Demonstrates the concept that electric current is a flow of electrons controlled by circuits. Describes have electrical circuits. Describes home electrical circuits and illustrates a short circuit caused by faculty insulation. Reveals functions of conductors and insulators, and measurements of electric flow by application of Ohm's law. Explains Ohm's law in terms of resistance, current, and electromotive force. For junior and senior high school, and adult groups.
