Question

Calculate the resistance of copper wire 50 m long and diameter 1 mm. Given resistivity of copper equals to 1.7x10-8 Ω-m

Answer 1

Answer:

R=1.08

Explanation:

Given l=50m

d=10^-3m

r=1/2*10^-3

a=πr²

resistivity=1.7*10^-8

Answer 2

Ans: 1.08 Ω  

Given l=50m

d=10^-3m

r=1/2*10^-3

a=πr²

resistivity=1.7*10^-8

solving part

R={( 1.7 * 10^-8) * (50)} / {(22/7) * 10^-6/4)}
