If firing angle in an SCR circuit is increased, the output ___________
Answer & Solution
Correct Answer:
Option
C
If the firing angle in an SCR (Silicon Controlled Rectifier) circuit is increased, the output is decreased.
The firing angle refers to the delay angle between the triggering signal and the conduction of the SCR. By increasing the firing angle, the SCR is triggered later in each cycle of the AC input voltage. This results in a shorter conduction period and therefore a decreased output from the SCR.
Therefore, the correct answer is Option C: Is decreased.
