In this video he teach how to calculate the electric field outside of a conductor.
Meyer talk about a structure made of binding material and conductive particles and talk about resistance everywhere..
Ceramics when wet become conductive specially if have impurities...
I was thinking what would be the electric field inside a resistor made of a two tube one inside the other? What's the electric field inside?
I mean what if we could build a cell made of 4 electrodes one inside the other having water in the middle and resistive material on the other two compartments?
I think I stumbled on something..
