Bipolar Junction Transistors (BJT) - Technical MCQs

Q1:

A transistor used in a digital circuit will have two operating states, which are cutoff and saturation.

A True

B False

ANS:A - True

Because in active region we do not consider the base resistance so when there is no base resistance then the base current will be zero it means that it will act like pen circuit so in open circuit it will act like a switch which is off.
