Viva Questions with answers:
What is a Rectifier?
A rectifier is a device which converts AC (Alternating current) to DC (Direct current).

Name the basic types of rectifiers?
Half wave rectifier, Full wave center tap rectifier and Full wave bridge rectifier.
What is the difference between Half Wave and Full Wave Rectifier?A half wave rectifier converts only half of the AC cycle to Uni-direction. Whereas a full wave rectifier converts both half cycles.

What is called ripple Voltage?
Ripple voltage in a rectifier output is the amount of AC content present in the output DC, it causes periodic pulsating of the DC voltage which is derived from the AC source.
What is the importance of PIV voltage of a Diode in A Rectifier Circuit?
PIV (Peak Inverse Voltage) is the maximum possible voltage that a diode can withstand in the reverse bias.
