Question

What is the resistance R of a length of copper wire whose length = 10m and whose diameter = 0.10 mm? Resistivity of copper is 1.7×10-8Ω-m

Answer 1

Answer:

hello mate..

Explanation:

When the resistance of copper wire is 0.1Ω and the radius is 1mm, then the length of the wire is (specific resistance of copper is 3.14×10-8ohm×m)
