Q1. How to convert from A.C to D.c. Supply
Ans. 
A.C to D.C. conversion can be done using a rectifier circuit.
• A rectifier circuit can be used to convert A.C. to D.C.

• The rectifier circuit can be half-wave or full-wave.

• Half-wave rectifier only allows half of the A.C. wave to pass through, while full-wave rectifier allows the entire wave.

• The rectifier circuit can be made using diodes.

• The output of the rectifier circuit is not smooth and requires filtering using capacito...read more
