A resistance and an inductance are connected in parallel and fed from 50 Hz ac mains. Each branch takes a current of 5 A. The current supplied by source is ____________(a) 10 A(b) 7.07 A(c) 5 A(d) 0 AThe question was posed to me by my college director while I was bunking the class.The question is from Relation between Hybrid Parameters with Short Circuit Admittance and Open Circuit Impedance Parameters in chapter Two-Port Networks of Network Theory

Answer» RIGHT choice is (B) 7.07 A

Easy EXPLANATION: The current is GIVEN by,

|5 – j5| = \(\sqrt{5^2 + 5^2}\)

= \(\sqrt{50} = 5\sqrt{2}\) = 7.07 A.
