Question

For the circuit shown, find the quiescent point.

(a) (10V, 4mA)

(b) (4V, 10mA)

(c) (10V, 3mA)

(d) (3mA, 10V)

I got this question by my school principal while I was bunking the class.

The above asked question is from DC Load Lines topic in section Transistor Characteristics of Electronic Devices & Circuits

Answer 1

Right answer is (c) (10V, 3mA)

The explanation is: We know, IE=VEE/RE=10/5kΩ=2mA

IC=α IE =IE =2mA

VCB=VCC-ICRL=20-10=10V. So, quiescent point is (10V, 2mA).
