For a Voltage divider bias circuit, having R1=R2=10KΩ, RC=4.7 KΩ, RE=1 KΩ, What is the value of collector current at saturation if VCC=10V?

(a) 1A

(b) 10mA

(c) 0.87mA

(d) 1ma

I have been asked this question by my school principal while I was bunking the class.

This interesting question is from The Operating Point in chapter Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits

Best answer
The correct option is (b) 10mA

The best I can explain: By using Thevenin’s law  Vth=VccR2/(R1+R2)=10V

 ICsat=VCC/(RC+RE)=0.87mA.
