What is the function of the emitter in a BJT?

• To amplify the signal passing through the base region.

• To absorb majority charge carriers from the base region.

• To regulate the flow of minority charge carriers.

• To emit or inject majority charge carriers into the base region.

What is the purpose of doping in a BJT?

• To reduce the number of layers in the BJT

• To create regions of different conductivity and control the flow of current.

• To increase the size of the BJT

• To make the BJT more resistant to temperature changes

What is the role of the base in a BJT?
