Question

The loss tangent refers to the

(a) Power due to propagation in conductor to that in dielectric

(b) Power loss

(c) Current loss

(d) Charge loss

I got this question by my school principal while I was bunking the class.

My doubt stems from Loss Tangent in chapter Maxwell Equations of Electromagnetic Theory

Answer 1

Right answer is (a) Power due to propagation in conductor to that in dielectric

To elaborate: The loss tangent is the tangent angle formed by the plot of conduction current density vs displacement current density. It is the ratio of Jc by Jd. It represents the loss of power due to propagation in a dielectric, when compared to that in a conductor.
