The ratio of conduction to displacement current density is referred to as

Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)

Dielectric constant

Attenuation constant

Loss tangent

Propagation constant

Correct Answer : Option (C) : Loss tangent

Explanation : Jc /Jd is a standard ratio, which is referred to as loss tangent given by σ /ε ω. The loss tangent is used to determine if the material is a conductor or dielectric.
