Find Z11, Z12, Z13 obtained from the mesh equations in the circuit shown below.(a) (8+j4) Ω, 5 Ω, 0Ω(b) (8-j4) Ω, 5 Ω, 0Ω(c) (8+j4) Ω, – 5 Ω, 0Ω(d) (8-j4) Ω, -5 Ω, 0ΩThis question was posed to me in unit test.My enquiry is from Mesh Analysis in division Steady State AC Analysis of Network Theory

Answer» CORRECT CHOICE is (d) (8-j4) Ω, -5 Ω, 0Ω

Best EXPLANATION: Z11= self impedance of LOOP 1 = (5 + 3 – j4) Ω. Z12 = Impedance common to both loop 1 and LOOP2 = -5Ω. Z13 = No common impedance between loop1 and loop 3 = 0Ω.
