The current gain of a transistor in common base mode is 0.99. What is the change in collector current if the emitter current changes by 5 mA ?

0.195 mA

4.95 mA

3.25 mA

0.495 mA

Text Solution

Verified by Experts

The correct Answer is:

`alpha= (DeltaI_C)/(DeltaI_E) therefore DeltaI_C = alpha xx DeltaI_E = 0.99xx5 `=4.95 mA
