In the circuit given below, a dc circuit fed by a current source. With respect to terminals AB, Thevenin’s voltage and Thevenin’s resistance are ____________(a) VTH = 5 V, RTH = 0.75 Ω(b) VTH = 0.5 V, RTH = 0.75 Ω(c) VTH = 2.5 V, RTH = 1 Ω(d) VTH = 5 V, RTH = 1 ΩThis question was posed to me in an internship interview.This question is from Advanced Problems Involving Complex Circuit Diagram in section Network Theory and Complex Circuit Diagram of Network Theory

Answer»

Correct ANSWER is (b) VTH = 0.5 V, RTH = 0.75 Ω

To explain: VTH = \(\frac{1 X 20}{40}\)X 1 = 0.5 V

Also, RTH = \(\frac{1 X 30}{40}\) = 0.75 Ω.
