Question

A circuit is given in the figure below. The Thevenin equivalent as viewed from terminals x and x’ is ___________ (a) 8 V and 6 Ω (b) 5 V and 6 Ω (c) 5 V and 32 Ω (d) 8 V and 32 Ω I got this question in an interview. The doubt is from Thevenin Theorem Involving Dependent and Independent Sources in chapter Useful Theorems in Circuit Analysis of Network Theory Select the correct answer from above options network theory questions and answers, network theory questions pdf, network theory question bank, network theory gate questions and answers pdf, mcq on network theory pdf, gate network theory questions and solutions, network theory mcq Test , ies network theory questions, Network theory Questions for GATE EC Exam, Network Theory MCQ (Multiple Choice Questions)

Answer 1

The correct choice is (b) 5 V and 6 Ω Best explanation: We, Thevenized the left side of xx’ and source transformed right side of yy’. Vxx’ = Vth = \(\displaystyle\frac{\frac{4}{8} + \frac{8}{24}}{\frac{1}{8} + \frac{1}{24}}\) = 5V ∴ Rth = 8 || (16 + 8) = \(\frac{8×24}{8+24}\) = 6 Ω.
