In CB configuration, the value of α=0.98A. A voltage drop of 4.9V is obtained across the resistor of 5KΩ when connected in collector circuit. Find the base current.

In CB configuration, the value of α=0.98A. A voltage drop of 4.9V is obtained across the resistor of 5KΩ when connected in collector circuit. Find the base current. Correct Answer 0.02mA

Here, IC=4.9/5K=0.98mA α = IC/IE .So, IE=IC/α=0.98/0.98=1mA. IB=IE-IC=1-0.98=0.02Ma.
