An SCR is turned off when ________________?
Correct answer: A. Anode current is reduced to zero
- A. Anode current is reduced to zero
- B. Gate voltage is reduced to zero
- C. Gate is reverse biased
- D. None of the above
Explanation
An SCR turns off when its anode current falls below the holding current, which is commonly approximated as reducing the current to zero. Removing or reversing the gate signal alone cannot turn off a conventional SCR after it has latched.
