Question

In a transistor 1 mA change in the emitter current,changes collector current by 0.99 mA. determine the a.c. current gain

Answer 1

By using the relation between collector current (IC) and base current (IB) you can find IC i.e.
IC = β*IB
IC = 1mA

Answer 2

Dear Student,

● Answer -

A.C. current gain in the transistor is 0.99.

◆ Explanation -

# Given -

∆Ie = 1 mA

∆Ic = 0.99 mA

# Solution -

A.C. current gain of the transistor is given by formula -

β = ∆Ic/∆Ib

β = 0.99 / 1

β = 0.99

Hence, A.C. current gain in the transistor is 0.99.

Thanks dear. Hope this is helpful to you...
