Calculate the conduction density of a material with resistivity of 0.02 units and electric intensity of 12 units.(a) 300(b) 600(c) 50(d) 120I have been asked this question in my homework.This question is from Maxwell Law 2 topic in division Maxwell Equations of Electromagnetic Theory

Answer»

The correct option is (b) 600

The BEST EXPLANATION: The conduction density is GIVEN by Jc = σE, where σ is the inverse of resistivity and it is 1/0.02 = 50. Thus we get, Jc = 50 x 12 = 600 UNITS.
