Description : A bipolar junction transistor (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, for ... base-collector junction is reverse biased (D) both the base-emitter and base-collector junctions are forward biased
Last Answer : A BJT is as a power control switch by biasing it in cut-off region (OFF state) or in the saturation region (ON state). In ON state, for BJT both the base-emitter and base- collector junctions are forward biased
