Bipolar Junction Transistors (BJT) - Technical MCQs

Q1:

Transistors are controlled to operate as a switch or to operate as a variable resistor.

A True

B False

ANS:A - True

When the q point is set in the active region, the transistor acts as an amplifier (variable resistor).

When the q point is set in the saturation region or in the cut off region, the transistor acts as a switch.
