1. How does the impedance of an electrode change with its surface area?  (increase / decrease)
2. How does the parallel capacitance (double-charge layer capacitance) of an electrode change by its surface area?   (increase / decrease)
3. Draw the electrical equivalence of an electrode/electrolyte interface using 4 passive electrical components.

1. The impedance is inversely proportional to the surface area so as the surface area of electrode increases its impedance decreases.

2.the parallel capacitance of an electrode is directly proportional to the surface area of electrode ao as the surface area increases the parallel capacitance also increases.

Pleaee post the last question seperately.. Thanx
