Q136 / 180 · KCET 2023 · Physics

A full-wave rectifier with diodes $D_1$ and $D_2$ is used to rectify $50 \mathrm{~Hz}$ alternating voltage. The diode $D_1$ conducts .......... times in one second.

  • A
    $100$
  • B
    $25$
  • C
    $75$
  • Correct answer
    D
    $50$

Solution

In full wave rectifier, one diode works for positive half cycle and another diode works for negative half cycle of alternating voltage. Thus, each diode works one time in one complete cycle of input AC signal. Hence, for $50 \mathrm{~Hz}$ AC supply, diode $D_1$ conducts 50 times in $1 \mathrm{~s}$.

Hence, the correct answer is option: 'D'.
