Diodes and Applications - Technical MCQs

Q1:

The dc current through each diode in a bridge rectifier equals:

A the load current

B half the dc load current

C twice the dc load current

D one-fourth the dc load current

ANS:A - the load current

In series configuration current is same, so during the positive half cycle of sine wave diode d1 and d3 will conduct through the load resister, so current will be same same thing commensurate for the the negative half cycle of the sine wave.
