A circuit consists of an excitation voltage VS, a resistor network and a resistor R. For different values of R, the values of V and I are as given, R = ∞, V = 5 volt; R = 0, I = 2.5 A; when R = 3 Ω, the value of V is __________(a) 1 V(b) 2 V(c) 3 V(d) 5 VThe question was asked in a national level competition.My doubt stems from Advanced Problems Involving Complex Circuit Diagram topic in portion Network Theory and Complex Circuit Diagram of Network Theory |
Answer» Correct choice is (c) 3 V |
