Question

In a full wave rectifier, for an input ac voltage

• A. the output voltage appears across the load for positive cycle only
• B. both diodes conduct during positive cycle
• C. both diodes conduct during negative cycle
• D. one diode is always forward biased and the other is always reverse biased
• E. a centre tapped transformer is used

Hint:

Bridge rectifier does not require a centre-tapped transformer, but the centre-tap configuration does.
