Bipolar Junction Transistors (BJT) - Technical MCQs

Q1:

The voltage gain of a transistor is inversely proportional to the change in output current.

A True

B False

ANS:A - True

Output voltage (Vc) is equal to Vcc - IcRc.

Based on this, we can say that when Ic INCREASES, the product of Ic and Rc increases which will result to a lower Vc where Vcc is held constant.

Voltage gain which is Vo/Vi thus DECREASES. Therefore, they are inversely proportional.
