Find the loss tangent of a material with conduction current density of 5 units and displacement current density of 10 units.(a) 2(b) 0.5(c) 5(d) 10I had been asked this question in an international level competition.My question comes from Loss Tangent topic in chapter Maxwell Equations of Electromagnetic Theory

Answer» RIGHT answer is (b) 0.5

To EXPLAIN: The loss tangent is the ratio of JC by Jd. On substituting for Jc = 5 and Jd = 10, the loss tangent, tan δ = 5/10 = 0.5. It is to be NOTED that it is tangent angle, so that the maxima and minima lies between 1 and -1 respectively.
