CORRECTION: In the video, the diode connected to the capacitor at the circuit output is unnecessary, so I removed it from the circuit diagram. The diode does not need to be used.
You can add Voltage and Ampere meter:
Note: When no load is connected to the output, the voltage value will be incorrect (because the capacitor is charging). The correct value is measured when the load is connected (motor, lamp, etc.). Capacitor can be canceled optionally.
