Consider a circuit having 3 identical Ammeters A1, A2, A3 parallel to one another. The 1^st Ammeter is in series with a resistance, the 2^nd Ammeter is in series with a capacitor and the circuit is excited by a voltage V. If A1 and A3 read 5 and 13 A respectively, reading of A2 will be? (a) 8 A (b) 13 A (c) 18 A (d) 12 A This question was addressed to me in an online interview. Question is from Advanced Problems Involving Complex Circuit Diagram in division Network Theory and Complex Circuit Diagram 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)

The correct option is (d) 12 A The best I can explain: We can infer from the circuit, A2 = \sqrt{13^2 – 5^2} Or, A2 = \sqrt{169 – 25} Or, A2 = \sqrt{144} Or, A2 = 12 A.
