Q1:

In a power supply diagram, which block indicates a smooth dc output?

A transformer

B filter

C rectifier

D regulator

ANS:D - regulator

Dc power supply with their basic parts.

Rectifier - converts sine wave input to pulsating DC output
Filter - smoothen the output of the waveform/reduce fluctuations
Regulator- provides constant/dc voltage and also maintains the output voltage at any load.
Load- recipient of the voltage

So, the answer is filter not a regulator.
