Transistors and Applications - Technical MCQs

Q1:

The beta of a BJT is the ratio of collector current to emitter current.

A True

B False

ANS:B - False

As alpha is the ratio of output current to the input current in common base mode. So,

Alpha = Ic/Ie.

Beta is the ratio of output current to the input current in common emitter mode. So,

Beta = Ic/Ib.

And gamma is the ratio of output current to the input current in common collector mode. So,

Gamma = Ib/Ie.
