Bipolar Junction Transistors (BJT)

Q1:

In a C-E configuration, an emitter resistor is used for:

A stabilization

B ac signal bypass

C collector bias

D higher gain

ANS:A - stabilization

When emitter resistance is there in the circuit. We will say circuit in stable. Because if temperature changes the operation of bjt also change it happens when emitter resistance is not there. To the bjt operation should be same at any time. We will use the emitter resistance.
