Diodes and Applications - Technical MCQs

Q1:

Providing a constant output regardless of ac input or load resistance changes is the function of a:

A transformer

B filter

C regulator

D rectifier

ANS:C - regulator

Rectifier produces pulsating dc output. Filter produce constant output. That is pulsating dc is passed to filter and produce constant output.

But best answer is voltage regulator as it contains both rectifier and filter. For Voltage regulator, zener diode and capacitor is used.
