A digital Multimeter reads 10 V when fed with a triangular wave, which is symmetric about the time-axis. If the input is same, the rms reading meter will read? (a) \frac{20}{\sqrt{3}} (b) –\frac{10}{\sqrt{3}} (c) –\frac{20}{\sqrt{3}} (d) \frac{10}{\sqrt{3}} I had been asked this question in homework. The origin of the question is Calculation of I(0+), di/dt(0+), d2I/dt2(0+) in Circuits Involving both Capacitor and Inductor in division Application of the Laplace Transform 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)

Right answer is (d) \frac{10}{\sqrt{3}} The explanation: For triangular wave Average value = \frac{V_m}{3} , rms value = \frac{V_m}{\sqrt{3}} ∴ \frac{V_m}{3} = 10 V or, Vm = 30 V.
