K5-43: NON-OHMIC DEVICE - V VS. I

ID Code: K5-43
Purpose: Demonstrates the non-linearity of the V vs I curve for a diode
Description: A zener diode is connected in series with a resistor across the output of a power supply. Observe the current vs. voltage as the voltage is varied. The voltage and current are read from projection meters when the device is placed on an overhead projector. The shunt with the zener diode has a series limiting resistor, so you will see a current in the milliamp range when the zener becomes conducting at about 7 volts
