Explanation: Collector current by the base current is beta, its value is in the range 50 to 300. 10. 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
Answer:A
Explanation: Collector current by the base current is beta, its value is in the range 50 to 300. 10. 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
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. Sanfoundry Global Education & Learning Series – Power Electronics.
