A Full Wave Rectifier Bridge With A Capacitor

  1. May 3, 2007 #1
    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 dont know wat is the current of the transformore :rofl:



    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
