Question

Order of rectifier circuits in decreasing ripple factor:

• A. A, B, C, D
• B. A, B, D, C
• C. D, C, A, B
• D. D, C, B, A

Hint:

Full-wave + filter gives best smooth DC (lowest ripple).

Answer 1

The Correct Option is B

Concept: Ripple factor indicates smoothness:
• Higher ripple → less smooth
• Lower ripple → more smooth

Step 1: Order (highest to lowest ripple)
• Half-wave without filter (highest)
• Full-wave without filter
• Half-wave with filter
• Full-wave with filter (lowest) \[ A \rightarrow B \rightarrow D \rightarrow C \] \[ \therefore \text{Correct answer is (B)} \]
