Question

5. What will be the resistivity of a metal wire of 2 m
length and 0.6 mm in diameter, if the resistance of
the wire is 50 ohms​

Answer 1

Find it out yourself

Answer 2

Answer:

ρ = 7.065  x 10^-6

Explanation:

given, l = 2m, r = 3x10^-4m, R = 50Ω

now,

resistivity ρ = RA/l

ρ = 50 x π x 9 x 10^-8 whole divided by 2

ρ = 7.065  x 10^-6
