This study designs and simulates a full wave bridge rectifier circuit equipped with components such as a capacitor filter and an IC 7809 regulator against variations in resistor and DC motor loads. The research method is carried out by designing and simulating using software, then variations of the resistor to observe the rectifier output waveform on a digital oscilloscope. The circuit consists of a step-down transformer, rectifier diode, capacitor, IC 7809 regulator, resistor and DC motor as a load variable. The simulation results show that the combination of a full wave bridge rectifier circuit with a capacitor filter and a voltage regulator produces a voltage of 7.35 - 7.37 V, a current of 0.36-0.37 A and a motor speed of 320 Rpm. In 10 experiments with a load variation of 100 - 1000 Ω, there was a change in voltage increase, and a decrease in current with a stable motor speed of 320 Rpm.
