For an SCR the total turn-on time consists of i) Delay time ii) Rise time and iii) Spread time During the rise time the a) anode current flows only near the gate b) anode current rises from zero to very high value c) losses are maximum d) anode to cathode voltage is zero

Explanation: The losses are maximum during the rise time because both Ia & Va are
high.
