1.	For metals, the conductivity will be(a) 0(b) 1(c) -1(d) InfinityI had been asked this question in a job interview.My doubt is from Dielectric vs Conductor Wave Propagation topic in section EM Wave Propagation of Electromagnetic Theory
Answer» Correct option is (d) Infinity Best EXPLANATION: Metals are PURE conductors. Examples are iron, copper etc. Their CONDUCTIVITY will be very high. THUS the metal conductivity will be infinity. Practically the conductivity of conductors will be maximum.
