(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Determine the potential [tex]\phi[/tex] inside a resistor of length l and radius a.

Also determine the current density J, resistance R, surface and volume charge density P_{e}and P_{es}. The resistor is homogeneous.

2. Relevant equations

3. The attempt at a solution

V=Ed, d=l here

V=El

E = J/[tex]\sigma[/tex]

So V= J/[tex]\sigma[/tex] l ?
