Determine the current I1 in the circuit shown below using mesh analysis.(a) 0.955∠-69.5⁰(b) 0.855∠-69.5⁰(c) 0.755∠-69.5⁰(d) 0.655∠-69.5⁰I had been asked this question in examination.My question is based upon Mesh Analysis topic in chapter Steady State AC Analysis of Network Theory

Answer» CORRECT option is (b) 0.855∠-69.5⁰

Explanation: The equation for loop 1 is I1(j4) + 6(I1-I2) = 5∠0⁰. The equation for loop 2 is 6(I1-I2) + (j3) I2 + (2) I2 = 0. SOLVING the above equations,I1 = 0.855∠-69.5⁰.
