How Capacitors Nearly DOUBLE AC Voltage #physics #engineering

[00:00:00]How does 10 volts become almost 20 volts? This circuit doubles voltage using only diodes and capacitors. An AC signal enters the circuit. During the first half cycle, one diode charges the capacitor. During the next half cycle, the second capacitor charges, too. Now, both capacitor voltages stack together, so the output becomes nearly double the input voltage. The capacitors also smooth the output to create stable DC power. That's why this circuit is called a voltage doubler.
