A 14-gauge copper wire of diameter 1.628 mm carries a current of 12.5 What is the potential difference across a 2.00 - m length of the wire? *p=1.47x10^-8

Explanation:

Given that,

The diameter of a wire, d = 1.628 mm

Radius, r = 0.814  mm = 0.000814m

Current, I = 12.5 mA

The length of the wire, l = 2m

The resistivity of the wire,

We need to find the potential difference across the wire. We know that the resistance of the wire is given by :

Also, V = IR

So, the potential difference of the wire is .

the inner core.

good luck: )
