In case of a R firing with R2 as the variable resistance, Vgp (peak of gate voltage) and Vgt (gate triggering voltage) the value of R2 is so adjusted such that

(a) Vgp = Vgt

(b) Vgp > Vgt

(c) Vgp < Vgt

(d) Vgp = Vgt = 0

The question was asked in an online interview.

Enquiry is from Firing Circuits-2 topic in division Other Circuits of Power Electronics

Right option is (a) Vgp = Vgt

To elaborate: For turning on the device, the peak of gate voltage must be equal to the gate triggering voltage.
