Hi Folks
I have posted this question earlier, but havent received convincing replies on it yet, so thought of putting it up again.
I have a parallel plate capacitor consisting of two metal plates (M), each coated with a thin layer of insulator (I). The coated plates are then placed at some distance from each other. Through the separation between them, a conducting fluid (S, saline with dielectric constant 80) is allowed to flow through.
So, effectively I have the schematic as:
M | I | S | I | M
and a sine voltage (100 mV p-p, 1 KHz) is applied between the two plates.
What would be the equivalent circuit model for such a system.
I am assuming it will be
-----| |--------| |--------| |------
| |
|--vvvvvv--|
which is three capacitors with a resistance in parallel with the middle capacitor.
The first one is the capacitance due to the coating on plate 1. Second capacitor is due to saline, in parallel with conductance of solution and third is again capacitor due to coating on plate 2.
