The r.m.s. value of the base current ofa transistor is `10mu`A. What is the current gain (`beta`) if the peak value of the a.c. collector current is 1.414 mA ?

A

50

B

75

C

100

D

125

Text Solution

Verified by Experts

The correct Answer is:
C
Peak value of `I_C` = 1.414 mA
`therefore` r.m.s. value of `I_C=1.414/sqrt2`= 1 mA
`therefore beta=I_C/I_B=10^(-3)/(10xx10^(-6)) ` =100
