Bipolar Junction Transistors (BJT) - Technical MCQs

Q1:

Base bias provides _________.

A a very stable Q point

B a very unstable Q point

C no current gain

D zero current in the base and collector circuits

ANS:B - a very unstable Q point

Since the Q point is determined by Ic and Vce a change in base bias (base current) Results in a change in Ic therefore the q point would also change.
