An experiment conducted at palestine technical university's electrical engineering department on a half wave rectifier circuit. The experiment involves recognizing and evaluating the peak-to-peak value and frequency of the wave, connecting a capacitor in parallel to the load resistor, and measuring the input and dc voltages. Equipment includes a diode, resistors, breadboard, capacitors, ac source, voltmeter, ammeter, and oscilloscope.
