Diodes and Applications - Technical MCQs

Q1:

Rectifier output polarity depends upon:

A cycles of input

B capacitor polarity

C half or full wave

D diode installation

ANS:D - diode installation

Whatever the type of rectifier the voltage will be dc voltage. So 3rd option is incorrect. Capacitor is generally used as a regulator. Therefore 2nd option is incorrect. The polarity of output voltage depends upon direction in which diodes are forward biased. Therefore 4th option is correct.
