Homework Statement
I was told that I can measure the "resistance" of a capacitor using 3 methods:
1. "The direct method"
[tex]R = \int_1^2 \frac{\rho}{A} ds[/tex]
2. "Ohm's Law"
[tex]R=\frac{U}{I}[/tex]
[tex]U=\int_1^2 E ds[/tex]
[tex]E=\rho J = \frac{\rho i}{A}[/tex]
3. "The analogy between electrostatics and electrokinetics"
[itex]\epsilon[/itex] is replaced by [itex]\sigma[/itex]
and
[itex]C[/itex] is replaced by [itex]G[/itex]
Homework Equations
What does this really mean, the resistance of the capacitor?
Why is [itex]E=\rho J[/itex]?
What is this analogy between electrostatics and electrokinetics?
