Question

For the circuit shown, find the quiescent point.

(a) (10V, 4mA)

(b) (4V, 10mA)

(c) (10V, 3mA)

(d) (3mA, 10V)

This question was posed to me during an online exam.

Question is from Problems on AC and DC Analysis topic in section Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Answer 1

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

The best I can explain: We know, IE=VEE/RE=30/10kΩ=3mA

IC=α IE =IE =3mA

VCB=VCC-ICRL=25-15=10V. So, quiescent point is (10V, 3mA).
