An SCR is turned off by _________________?
Correct answer: A. Reducing anode voltage to zero
- A. Reducing anode voltage to zero
- B. Reducing gate voltage to zero
- C. Reverse biasing the gate
- D. None of the above
Explanation
Reducing the anode voltage to zero removes forward bias and turns the SCR off. More generally, an SCR turns off when its anode current falls below the holding current, so merely removing gate voltage would not turn it off.
