A transistor connected in common emitter configuration has input resistance `R_("in")=2 K Omega` and load resistance of `5 K Omega` . If `beta=60` and an input signal 12 mV is applied , calculate the resistance gain, voltage gain and power gain.

Options

A. 2.5,150,9000
B. 4.5,150,9000
C. 2.5,200,9000
D. 2.5,150,9500

Answer

A

Explanation

`A_(r)=(R_(0))/(R_(i))`
`=(5)/(2)=2.5`
`A_(v)=beta*(R_(0))/(R_(i))=60xx2.5`
`A_(p)=A_(v)xxbeta=150xx60`
=9000
