A common emitter amplifier gives an output of 3 V for an input of 0.01 V. If `beta` of the resistance is 100 and the input resistance is `1 kOmega`. then the collector resistance is

A

`3 kOmega`

B

`30 kOmega`

C

`1 kOmega`

D

`5 kOmega`

Text Solution

Verified by Experts

The correct Answer is:
A

`A_V=V_o/V_i=betaR_o/R_i`
or `R_o=(V_oR_i)/(V_ibeta)=(3xx1xx10^3)/(0.01xx100)=3 kOmega`
