A given wire of resistance 10ohm has a length of 5m and a cross sectional area of 4.0*10^-3m^2,calculate the conductivity of the wire .

please help me out I don't understand it

1 answer

you know that conductivity is measured in 1/Ω-m
Recall that conductivity σ = L/RA
You have the numbers, so plug them in.
