Question

With respect to the potential of emitter, base and collector, a $\text{NPN}$ 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 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

Answer: (B)

The transistor conducts in active state in which and input circuit is forward biased and output circuit is reversed biased
