A) \[\beta ={{\left( \frac{\Delta {{l}_{C}}}{\Delta {{l}_{B}}} \right)}_{{{V}_{CE}}}}\]
B) \[\beta ={{\left( \frac{\Delta {{l}_{B}}}{\Delta {{l}_{C}}} \right)}_{{{V}_{CE}}}}\]
C) \[\beta ={{\left( \frac{\Delta {{l}_{C}}}{\Delta {{l}_{E}}} \right)}_{{{V}_{CE}}}}\]
D) \[\beta ={{\left( \frac{\Delta {{l}_{E}}}{\Delta {{l}_{C}}} \right)}_{{{V}_{CE}}}}\]
Correct Answer: A
Solution :
The AC current gain in an common-enitter transistor is denned as the ratio of the change in the collector current to the change in the base current at a constant collector to emitter voltage \[\beta ={{\left( \frac{\Delta \,{{i}_{C}}}{\Delta \,{{i}_{B}}} \right)}_{{{V}_{CE}}}}\]You need to login to perform this action.
