Question

The Thevenin’s equivalent of a network is a 10 V source in series with 2 Ω resistances. If a 3 Ω resistance is connected across the Thevenin’s equivalent is _____________ (a) 10 V in series with 1.2 Ω resistance (b) 6 V in series with 1.2 Ω resistance (c) 10 V in series with 5 Ω resistance (d) 6 V in series with 5 Ω resistance The question was asked by my college professor while I was bunking the class. The doubt is from Series-Parallel Interconnection of Two Port Network in chapter Two-Port Networks 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

Correct option is (b) 6 V in series with 1.2 Ω resistance Easiest explanation: The Thevenin equivalent voltage is given by, VTH = \frac{10 X 3}{5} = 6 V And the Thevenin equivalent Resistance is given by, RTH = \frac{3 X 2}{5} = 1.2 Ω.
