Question

The current-gain of a transistor in a common-base arrangement is 0.98. Find the change in collector-current corresponding to a change of 5.0 mA in emitter-current. What would be the change in the base-current?

easy

Solution

Correct option is

4.9 mA, 0.1 mA

By definition, the a-c current-gain in common-base arrangement of a transistor is give by

= 4.9 mA.

We know that the base-current is emitter-current minus collector-current, that is

= 0.1 mA.
