If firing angle in an SCR circuit is increased, the output _____________?
Correct answer: C. Is decreased
- A. Remains the same
- B. Is increased
- C. Is decreased
- D. None of the above
Explanation
Increasing the firing angle delays SCR turn-on, leaving less of each cycle for conduction and generally reducing the rectifier's average output. The exact waveform changes with circuit type, but this is the standard controlled-rectifier relationship.
