Question

The common base dc current gain of a transistor is o. 967. If the emitter current is 10 MA, What is the value of collector current ?​

Answer 1

Answer:

Given:

Current gain (α)=0.967

Emitter current =10mA

To find:

The value of base current of the transistor = ?

Solution:

The common gain DC current us is given by,
