Purpose: Demonstrate a transistor circuit.
Description: A high-current transistor controlled by a flashlight battery operates an automobile headlamp by switching a 7.5 volt heavy duty dry cell onto the light. The circuit for the system is shown above, and is included with the demonstration. By removing and replacing wires it can be shown that the flashlight battery alone cannot operate the light and that the heavy duty dry cell connected directly to the light turns the light on.
