Electrical current ohm’s law

In spite of ever expanding use of EIS in analysis of practical and experimental systems, the impedance (or complex electrical resistance for a lack of a better term) fundamentally remains a simple concept. Electrical resistance R is related to the ability of a circuit element to resist the flow of electrical current. Ohm s law (Eq. 1) defines resistance in terms of the ratio between input voltage V and output current I ... 

See, H.J.V. Tyrrell and K.R. Harris, Diffusion in Liquids, Bucterworths, London, 1984, Chapter I. There are also analogies with the flow of heat (Fourier s law) and of electric current (Ohm s law) much of the mathematics is formally similar. 

One of the most important electrical characteristics of a solid material is the ease with which it transmits an electric current. Ohm s law relates the current /—or time rate of charge passage—to the applied voltage V as follows ...
