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
