  1. In a bridge rectifier, current flows through two diodes during both positive and negative half cycles, leading to very high-power loss.
  2. The peak inverse voltage (PIV) of diode in a bridge rectifier is the same as in a center-tapped rectifier.
  3. The output voltage of a bridge rectifier consists of only DC components with no AC ripples.
  4. The bridge rectifier is a full-wave rectifier that does not require a center tapped transformer, improving transformer efficiency.

The statement that best describes the operation of a bridge rectifier is: 4) The bridge rectifier is a full-wave rectifier that does not require a center tapped transformer, improving transformer efficiency.

Explanation:
Bridge Rectifier Overview: A bridge rectifier is a full-wave rectifier circuit that uses four diodes arranged in a bridge configuration to convert both positive and negative half-cycles of an AC input into a pulsating DC output.

It does not require a center-tapped transformer, unlike a center-tapped full-wave rectifier, which makes it more efficient in terms of transformer utilization.
