Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)
Find the resistance of a cylinder of area 200 units and length 100m with conductivity of 12 units.
A)
1/12
B)
1/24
C)
1/48
D)
1/96

Correct Answer : Option (B) :   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.
