Question

A n-p-n 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 base

(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 1

The correct option is (b) collector is positive and emitter is negative with respect to the base.

Explanation:

A n-p-n transistor conducts when emitter-base junction is forward biased while collector-base junction is reverse biased.
