While a collector to emitter voltage is ...

While a collector to emitter voltage is constant in a transistor, the collector current changes by `8.2 mA` when the emitter current changes by `8.3 mA`. The value of forward current ratio `h_(fe)` is

A

82

B

83

C

`8.2`

D

`8.3`

Text Solution

Verified by Experts

The correct Answer is:
A
`h_(fe)=beta=(DeltaI_(C))/(DeltaI_(B))=(8.2xx10^(-3))/((8.3-8.2)xx10^(-3))=82`
