Answer / Ravi Prakash

Bipolar Junction Transistor (BJT) is called a current control device because the base current controls the current flowing through the collector-emitter in linear mode. In other words, for a given voltage drop across the base-emitter junction, the collector current can be adjusted by changing the base current. This property makes BJT useful as an amplifier, switch, and regulator.
