In full wave rectification the output D.C. voltage across the load is obtained for_____________?
Correct answer: C. The complete cycle of input A.C.
- A. The positive half cycle of input A.C.
- B. The negative half cycle of input A.C.
- C. The complete cycle of input A.C.
- D. All of the above.
Explanation
A full-wave rectifier uses both the positive and negative half cycles of the AC input, but reverses the negative half so the load current remains in one direction. Therefore, a DC output is obtained throughout the complete AC cycle. The common mistake is choosing the positive half cycle, which describes half-wave rectification.
