The transistor parameters, namely

α

and

β

of a transistor are related as

PhysicsSemiconductorsNEET

Options:

A $\frac{1}{α} + \frac{1}{β} = 1$
B $\frac{1}{α} = β + \frac{1}{β}$
C $\frac{1}{α} - \frac{1}{β} = 0$
D $\frac{1}{α} - \frac{1}{β} = 1$

Solution:

The correct answer is:

\frac{1}{α} - \frac{1}{β} = 1

For common-emitter transistor.

β = \frac{α}{1 - α} \Rightarrow \frac{1 - α}{α} = \frac{1}{β}

or

\frac{1}{α} - \frac{1}{β} = 1
