Question

Calculate the resistance of a copper wire of length 5 metre having radius as 5mm. (given the resistivity of copper is 1.68 x 10 -8 ohm metre.

Answer 1

Answer:

5 metre having radius as 5mm. (given the resistivity of copper is 1.68 x 10 -8 ohm metre.

Explanation:

5 metre having radius as 5mm. (given the resistivity of copper is 1.68 x 10 -8 ohm metre.

A resistance of 2 ohm is to be made from a copper wire specific resistance 1.7 into 10 raise to minus 6 ohm metre using a wire of length 50 cm the radius of the wire is
