A transistor has a current gain of 30. If the collector resistance is `6kOmega`, input resistance is `1kOmega`, calculate its voltage gain?

A

90

B

180

C

45

D

360

Text Solution

Verified by Experts

The correct Answer is:
B
Voltage gain = current gain x resistance gain
=current gain x `R_C/R_I=30xx6/1=180`
