A power BJT is used as a power control switch by biasing it in the cut off region (off state) or in the saturation region (on state). In the on state

(a) both the base-emitter & base-collector junctions are forward biased

(b) the base-emitter junction is reverse biased, and the base collector junction is forward biased

(c) the base-emitter junction is forward biased, and the base collector junction is reversed biased

(d) both the base-collector & the base-emitter junctions are reversed biased

I had been asked this question by my school teacher while I was bunking the class.

The origin of the question is Power Transistor-1 topic in division Power Electronics Devices of Power Electronics

Correct option is (a) both the base-emitter & base-collector junctions are forward biased

The explanation: When base-emitter & base-collector junctions are forward biased only than both the p-n junctions are forward biased and the device is on.
