1.	length of wire is 200 cm, area of the wire 20m^2 the resistance of the wire 4 ohm find the resistivity??
Answer» R = 4 l = 200CM = 2m A = 20 m^2 ρ = ? Formula is R = ρ * l / a 4 = ρ * 2 / 20 ρ = 4 * 20 / 2 ρ = 40 ohm.m

length of wire is 200 cm, area of the wire 20m^2 the resistance of the wire 4 ohm find the resistivity??

Answer»

R = 4

l = 200CM = 2m

A = 20 m^2

ρ = ?

Formula is R = ρ * l / a

4 = ρ * 2 / 20

ρ = 4 * 20 / 2

ρ = 40 ohm.m
