This document outlines an electronics lab experiment on measuring the I-V characteristic of a Zener diode. The experiment uses a DC power supply, Zener diode, resistor, and multimeter to build a circuit. Students will connect the circuit, vary the applied voltage and measure the corresponding output voltage and current readings. They will record the data in a table and plot a graph of voltage versus current to analyze the Zener diode's behavior under reverse bias and forward bias conditions. Students are expected to submit an individual lab report containing the topic, circuit diagram, procedure, data table, equipment list, and graph.
