Find the resistance of a cylinder of area 200 units and length 100m with conductivity of 12 units.(a) 1/24(b) 1/48(c) 1/12(d) 1/96I got this question in an internship interview.Query is from Continuity Equation in section Electric Fields in Material Space of Electromagnetic Theory

Answer» RIGHT option is (a) 1/24

Explanation: The resistance is GIVEN by R = ρL/A = L/σA. Put L = 100, σ = 12 and A = 200, we get R = 100/(12 x 200) = 1/24 UNITS.
