A wire of length 100cm and cross-sectional area of 2.0 x 10-3cm2 has a resistance of 0.10 Ω. Calculate its electrical conductivity.?

Answer 1

if you know the definition of conductivity, and watch the units, the answer should be clear.

Answer 2

P = RA/L = 0.1*(2*10^-3)/(1*10^2) = 2*10^-6 ohm*cm. = resistivity.
Conductivity = 1/P =

Answer 3

conductivity = 1/P siemens/meter.
