For a R firing circuit, the maximum value of source voltage is 100 V. Find the resistance to be inserted to limit the gate current to 2 A.

(a) 5 Ω

(b) 50 Ω

(c) 500 Ω

(d) 0.5 Ω

I had been asked this question in an interview for internship.

I'm obligated to ask this question of Firing Circuits-2 topic in chapter Other Circuits of Power Electronics
