Question

A current waveform is of the shape of a right angled triangle with period of t = 1 sec. Given a resistance R = 1 Ω. The average power is __________ (a) 1 W (b) 0.5 W (c) 0.333 W (d) 0.111 W I had been asked this question during an online interview. I would like to ask this question from Advanced Problems on Network Theorems topic 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

Right choice is (d) 0.111 W To explain: We know that RMS current is, I = 1 \( \int_0^1 (1t)^2 \,dt\) = \( \int_0^1 t^2 \,dt\) = \(\frac{1}{3}\) A Now, power P = I^2R = \(\frac{1}{9}\) X 1 = 0.111 W.
