This document describes an electronics lab experiment on implementing a half wave rectifier using a diode. The objectives are to build a half wave rectifier circuit using a diode, load resistance, capacitor, oscilloscope and signal generator. The procedure instructs how to connect the components, observe the rectified output on an oscilloscope, and measure input and output voltages with and without the capacitor. A lab report is required with the circuit diagram, procedure, measurements, equipment list, and expected output graph.
