    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

    Correct Answer: B

    Solution :

    [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
