In a half wave rectifier, the r.m.s value of the A.C. component of the wave is

A

equal to d.c. value

B

more than d.c. value

C

less than d.c. value

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B
The r.m. s. value of a.c. component of wave is more than d.c. value due to barrier voltage of p - n junction used as rectifier.
