Hiya!(adsbygoogle = window.adsbygoogle || []).push({});

I have a problem thats got me confused to solve. I wanna use ohms law but not right. Here is the problem.

A nichrome wire has a radius 0f .5 mm and resistivity of 100 x 10^-8 ohm.m. If the wire carries a current of .5 A what is the voltage across the wire? The length of the wire is .32m

E = .5A x 100 x 10^-8 ohm is what i have for setting it up but its not the answer. what do i need to do to solve for this?
