Question

Consider a resistive network circuit, having 3 sources of 18 W, 50 W and 98 W respectively and a resistance R. When all source act together the maximum and minimum power is ____________ (a) 98 W, 18 W (b) 166 W, 18 W (c) 450 W, 2 W (d) 166 W, 2 W I had been asked this question in a job interview.

Answer 1

The correct choice is (c) 450 W, 2 W The best I can explain: Let us suppose R = 1 Ω Then, I1 = 32 A, I2 = 52 A and I3 = 72 A Or, (I1 + I2 + I3)^2 R = (152)^2 R = 450 Ω.
