Diagram Transformerless Power Supply 12v 5a

This capacitor drops the voltage and gives the low output voltage.

Diagram transformerless power supply 12v 5a.

Now you may say that why we used a series capacitor not a resistor as the resistor also can drop the voltage. 24v 2a power supply circuit. We can convert the high voltage ac into low voltage such as 5v 6v 9v 12v dc without using the transformer which is called transformerless power supply. Simple variable current power supply 12v 1a 5a.
