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:-

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
