Wrong! - Continue >> Which of the following devices does not belong to the transistor family? BJT MOSFET IGBT GTO Correct! Wrong! - Continue >> A power transistor is a three layer, two junction device two layer, one junction device four layer, three junction device three layer, three junction device Correct! Wrong! - Continue >> 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 the base-emitter junction is forward biased, and the base collector junction is reversed biased the base-emitter junction is reverse biased, and the base collector junction is forward biased both the base-emitter & base-collector junctions are forward biased both the base-collector & the base-emitter junctions are reversed biased Correct! Wrong! - Continue >> In a power transistor, _________ is the controlling parameter. VBE VCE IB IC Correct! Wrong! - Continue >> In a power transistor, the IB vs VBE curve is an exponentially decaying curve a straight line Y = IB resembling the diode curve a parabolic curve Correct! Wrong! - Continue >> In a power transistor, ____ is the controlled parameter. IB VCE IC VBE Correct! Wrong! - Continue >> A power transistor is a _________ device. two terminal, unipolar, current controlled two terminal, bipolar, voltage controlled three terminal, bipolar, current controlled three terminal, unipolar, voltage controlled Correct! Wrong! - Continue >> For a power transistor, if the base current IB is increased keeping VCE constant, then IC decreases none of the mentioned IC remains constant IC increases Correct!
