An npn transistor operates as a common emitter amplifier with a power gain of `10^6`. The input circuit resistance is `100 Omega` and the output load resistance is `10 k Omega`. The common emitter
current gain '`beta`' will be (Round off to the Nearest Integer)

Text Solution

Verified by Experts

The correct Answer is:
100
Power gain `beta^2xxR/r`
`10^6xxbeta^2xx(10xx10^3)/100`
`beta^2=100xx100`
`beta=100`
