Homework Statement



Two inflnitely long, straight, parallel Wires are embedded in an infmite medium of conductivity 2 Sm-1. The wires are identical, with a round cross-section of radius 0.25 cm. The centres of the wires are 1 cm apart. Find the conductance per metre between the wires.

A) 0.76 Sm-1
B) 1.19 Sm-1
C) 3.05 Sm-1
D) 4.77 Sm-1

Homework Equations



J = σE
∫D∙ds = ∫ρdv = Q or ∇∙D = ρ
D = εE
