Question

In a bridge rectifier, during the positive half cycle, which diodes conduct?
  1. A
    All four diodes
  2. B
    The two diodes forming one diagonal
    Correct
  3. C
    The two diodes forming the other diagonal
  4. D
    Only one diode

Correct answer

The two diodes forming one diagonal

Explanation

In a bridge (D₁, D₂, D₃, D₄): during positive half cycle, D₁ and D₃ conduct (one diagonal); during negative half cycle, D₂ and D₄ conduct (other diagonal). Both half cycles produce current through the load in the same direction.
