A Full Wave Rectifier Bridge With A Capacitor

[zouzanda]

1. i have a transformor 12 v rms i want to do a full wave rectifier bridge with a capacitor and get a 12v dc



2. i need to know how i can calculat the capacitor needed and the resistor and wat to know how many voltage should the capacitor be (NB: i don't know wat is the current of the transformore



3. i have done the bridge and its working

1. Why do you think this will give you 12v DC?
2. I don't understand your question.

hey

ok ill try to explain i have a transformer its from 220V to 12v i did a diode bridge for it and i measured the voltage by the multymeter it shows 12 v. but the thing is i need to add a capacitor to the bridge and a resistor to decrease the ripple and i donno how much the capacitor should be how many farad and how much its voltage
