MHT CET Physics question

Not in JEE Advanced syllabus

A NPN transistor conducts when

(A)Both collector and emitter are positive with respect to the base
(B)Collector is positive and emitter is negative with respect to the baseCorrect
(C)Collector is positive and emitter is at same potential as the base
(D)Both collector and emitter are negative with respect to the base

Answer: (B)

Solution

An n-p-n transistor conducts when the emitter-base junction is forward biased (emitter negative w.r.t. base) and the collector-base
