How to make power supply using transformer // step down transformer power supply

 To make power supply you need Step down Transformer , if you need 12v you need 12 volt transformer and amp of transformer is depend on your load.

Hear i am using 12 0 12 1 amp Transformer 

MAKING PROCESS-

First we need zero PCB to Placed the circuit

Then 4 peace of in4007 diode arrange in this manner 

Next we need Capacitor To filter the output supply

And then We need Voltage Regulated IC7812 to get constant Voltage

And Last but not least we need 1k resistance and LED to Indication in Circuit is on
