. If =0.98 ,Ico=6µA and Iβ=100µA for a transistor,then the value of Ic will be______?
Correct answer: D. 5.2mA
- A. 2.3mA
- B. 3.2mA
- C. 4.6 mA
- D. 5.2mA
Explanation
Using IC = α(IB + IC) + ICO gives IC = (αIB + ICO)/(1 − α) = (0.98 × 100 μA + 6 μA)/0.02 = 5.2 mA. This includes both the common-base leakage contribution and the collector current from transistor action.
