1.	Copper behaves as a(a) Conductor always(b) Conductor or dielectric depending on the applied electric field strength(c) Conductor or dielectric depending on the frequency(d) Conductor or dielectric depending on the electric current densityThis question was posed to me during an online exam.My question comes from Advanced and Tricky Questions topic in portion Advanced and Tricky Questions of Electromagnetic Theory
Answer» The correct option is (a) CONDUCTOR always The EXPLANATION: The LOSS tangent for copper is very large due to its high conductivity. This SHOWS that the copper BEHAVES as a conductor in all conditions.
