The current gain beta of a transistor is 50 the input resistance of a transistor,when used in the common emitter configuration,is 1komega.the peak value of collector a.c current for an alternating peak input voltage 0.01v is

Answered by admin @


The peak value of collector A.C current is 500μA.

Explanation:

Given data:

Beta of transistor "β" =50

Emitter configuration "Ri" =1 KΩ = 10^3Ω  

Vc = 0.01 V

= 10^−2V

Iβ = 10^−2 / 10^+3

   = 10^-5

IC = βIβ

   = 50×10^−5

   =500×10^−6 A  

   = 500μA

Hence the peak value of collector A.C current is 500μA
