For the same secondary voltage, the output voltage from a centre-tap rectifier is___________ than that of bridge rectifier?
Correct answer: D. one-half
- A. twice
- B. thrice
- C. four time
- D. one-half
Explanation
With the same total secondary voltage, a centre-tap rectifier uses only half the secondary winding during each half-cycle, while a bridge uses the full secondary. Thus the centre-tap output voltage is one-half of the bridge output voltage.
