    If a full wave rectifier circuit is operating from 150 Hz mains, the fundamental frequency in the ripple will be

    A)  75 Hz              

    B)  150 Hz              

    C)  300 Hz                        

    D)  600 Hz

    Correct Answer: C

    Solution :

    In a full wave rectifier, the fundamental frequency in ripple is twice of input frequency. Hence, the fundamental frequency in the ripple \[= \,\,2 \times  operating frequency\] \[=\,\,\,2\times 150\] \[= \,\,300 Hz\]
