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 base

C

Collector is positive and emitter is at the

D

Both collector and emitter are negative with respect to the base

Text Solution

Verified by Experts

The correct Answer is:
B
When the collector is positive and emitter is negative w.r.t. base, it causes the forward biasing for each junction, which causes conduction of current.
