Question

 Half wave rectifier passes only ____.

Options
  • A

    Lower half cycle

  • B

    Upper half cycle

  • C

    Both cycles

  • D

    None of them

Explanation

Positive half cycles of the applied input voltage. It blocks the negative half cycles and converts AC (alternating current) to DC (direct current).

The half-wave rectifier passes only the positive half cycles of the input voltage, not the upper half cycle.

OPTIONS A, B & C are incorrect.

Positive half cycles of the applied input voltage. It blocks the negative half cycles and converts AC (alternating current) to DC (direct current).

The half-wave rectifier passes only the positive half cycles of the input voltage, not the upper half cycle.
