8.2.2 Electrochemical Impedance Spectroscopy
It is well known that electrical resistance is the ability of a circuit element to
resist the ow of electrical current. For a ow of DC current i to an applied
DC potential E, the resistance is given by Ohm’s law as
R
E
i
= . (8.2)
However, in the real world, circuit elements exhibit much more complex
behavior; the simple concept of resistance cannot be used and in its place, imped-
ance, a more general circuit parameter, is used. Like resistance, impedance is the
ability of the system to impede the ow of electrical current through it. Though
it is similar to resistance, impedance is ...
