When the base current in a transistor is...

When the base current in a transistor is changed from `30 mu A`to `80 mu A`,the collector current is changed form 1.0 mA to 3.5 mA. Find the current gain`beta`.

Text Solution

Verified by Experts

We know that `beta=(Deltai_(c))/(Deltai_(B))`
`=((3.5-1.0)xx10^(-3))/((80-30)xx10^(-6))=50`
