In a common base transistor amplifier if the input resistance `R_(i)` is 200 `Omega` and load resistance `R_(L)` is `20K Omega` , find voltage gain `(alpha=0.95)`

A

86

B

98

C

95

D

190

Text Solution

Verified by Experts

The correct Answer is:
C
`R_(i)=200 Omega, R_(0)=20 K Omega, A_(v)= ? Alpha=0.95`
Now `A_(v)=alpha(R_(0))/(R_(i))`
`=0.95xx(2000)/(200)=0.95xx200=190`
