For a certain transistor, if the value of Beta is equal to 500 and Base current is 5mA, then the value of Emitter current is:-
For a certain transistor, if the value of Beta is equal to 500 and Base current is 5mA, then the value of Emitter current is:-
Right Answer is:
2.505
SOLUTION
Given Base current IB = 5mA
Current Gain β = 500
The dc current gain βdc is defined as the ratio of collector current to base current at a constant VCE under dc biasing conditions.
β = IC/IB
500 = IC/50
IC = 2500 mA
The emitter current is
IE = IB + IC
IE = 50 +2500
IE = 2505mA = 2.505 A
