Question

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

Answer 1

The correct option is B more than d.c. value

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.
