Question
The value of current gain α of a transisitor is 0.98. The value of β will be
Options
A.490
B.4.9
C.59
D.49
Solution
α = 
and β =
[Ic, Ib and Ie are collector, base and emitter current]
Ie = Ic + Ib ⇒
= 1 + 
= 1 + 
⇒ β = 
=
= 49
and β = [Ic, Ib and Ie are collector, base and emitter current]
Ie = Ic + Ib ⇒
= 1 + = 1 + ⇒ β = =
= 49Create a free account to view solution
