These are really flaming big hintsFollow the current in the full bridge rectifier , how many diodes does it actually go through ? The voltage drop in a diode is roughly 0 . 7 V , sum up the voltage drops . Vdroptotal Vdrop 1 Vdrop 2 . The peak current will occur when you have peak voltage , you supply a fullwave rectifier with a wave of electricity . So find the peak voltage , and use Ohm ' s law to find the peak current through the loadresistorwhatever the question wants . Ipk VpkROn average current , you will use the average voltage of the wave . The average voltage on an AC voltage is called the RMS voltage . So use the RMS voltage to determine the current .
