Darlington's Question ?

Hello dear ,
Can you help me to solve a question in darlington ?

How to find the current through the 50 ohm resistor ?

KonstanU · Jan 2, 2013

I = (2.5V-Vbe*2)/50. Roughly, Vbe equals 0.7V. So you have current about 28mA.

Thank you dear
correct answer.
I have been a confused because of the 500 ohm base resistor.This means that it doesn't have any effect on the circuit ?

KonstanU · Jan 2, 2013

Not so but it has negligible effect. It effects on the voltage level of Vbe.Q1
