In pure dielectrics, the parameter that is zero is(a) Attenuation(b) P

1.	In pure dielectrics, the parameter that is zero is(a) Attenuation(b) Propagation(c) Conductivity(d) ResistivityThis question was posed to me during an internship interview.This is a very interesting question from Plane Waves in Dielectrics topic in chapter EM Wave Propagation of Electromagnetic Theory
Answer» The CORRECT option is (c) Conductivity Explanation: There are no free charge carriers available in a DIELECTRIC. In other words, the charge carriers are PRESENT in the valence BAND, which is very difficult to start to conduct. Thus conduction is low in dielectrics. For pure dielectrics, the conductivity is assumed to be zero.
