Find the common impedances Z12, Z13, Z21, Z23, Z31, Z32 respectively in the circuit shown below.(a) -j3Ω, 0Ω, -j3Ω, j5Ω, 0Ω, j5Ω(b) j3Ω, 0Ω, -j3Ω, j5Ω, 0Ω, j5Ω(c) j3Ω, 0Ω, -j3Ω, j5Ω, 0Ω,- j5Ω(d) j3Ω, 0Ω, -j3Ω, -j5Ω, 0Ω, j5ΩI had been asked this question during an online interview.I'm obligated to ask this question of Mesh Analysis topic in section Steady State AC Analysis of Network Theory

Answer»

The CORRECT answer is (a) -j3Ω, 0Ω, -j3Ω, j5Ω, 0Ω, j5Ω

To EXPLAIN: The COMMON IMPEDANCES Z12 and Z21 are Z12 = Z21 = -j3Ω. The common impedances Z13 and Z31 are Z13 = Z31 = 0Ω. The common impedances Z23 and Z32 are Z23 = Z32 = j5Ω.
