Hello every one,
I need some help.
I want to make a bridge rectifier circuit to give me 6v or 9v DC power from 220v to 250 v . I know the circuit, but don't know which diodes and capacitors need to use for getting 6v or 9v . The circuit was same as following figure .




I have seen this circuit in my LED light charger to charge the light's battery.
I want to make a circuit for output volt 6 and 9 v .
Please help me if any one have any idea about this circuit .
Please tell me
R1 = ?
C=? (may b Polyester Capacitor)
for getting 6 and 9 v

Hello,

You can better use a circuit that uses a transformer to bring down the voltage.

I am closing this thread as it violates AAC policy and/or safety issues.
