Question
The thyristor is turned off when the anode current falls below-
The correct answer is
Holding current
The holding current is the minimum anode current required to maintain the thyristor in the conducting state. While reducing the forward current is necessary for turn-off, the specific threshold is the holding current, not just any forward current value.
