If the base width in a bipolar junction transistor is double witch one of the following statements will be true

Question

If the base width in a bipolar junction transistor is doubled, which one of the following statements will be TRUE? 

(a) Current gain will increase 

(b) Unity gain frequency will increase. 

(c) Emitter – base junction capacitance will increase. 

(d) Early voltage will increase

Answer 1

Correct option (d) Early voltage will increase

Explanation:

As the base width is increased, the base current will increase thus reducing the collector current. The collector– emitter characteristics will be more flat, thus the extrapolation of collector currents will be farther i.e. Early voltage will increase.
