General Science - Physics MCQs

Q.  What is the ratio of the change in collector current to the change in base current at a constant collector-emitter voltage, when the common emitter transistor is in active state, known as?

a. Input resistance
b. Output resistance
c. Current amplification factor
d. None of the above


ANSWER: See Answer
 
Current amplification factor β: This is defined as the ratio of the change in collector current to the change in base current at a constant collector-emitter voltage (VCE) when the transistor is in active state.
