In a common emitter amplifier the load resistance of the output circuit is 1000 times the load resistance of the input circuit. If `alpha=0.98`, then the voltage gain is `axx10^(4)`. The integer value of a is.

Text Solution

Verified by Experts

`beta=alpha/(1-alpha)=0.98/(1-0.98)=49`
`A_(V)=betaR_(o)/R_(i)=49xx1000=4.9xx10^(4)~~5xx10^(4)`
