Question

Bipolar junction transistor (BJT) is a voltage controlled device. state True or false, also give reason of your answer.

Answer 1

In a BJT, if we applay an electric field across the base-emitter junction ,then decreases the width of the depletion zone. This electric field, measured in volts, controls the movement of charge carriers. Therefore the BJT is voltage controlled.

So, the statement is true. BJT is voltage controlled device.
