What is Ohm's Law in chemistry ?

Electrolytic conductors, like metal conductors, follow Ohm's law. Accordingly, in this law, the current flowing through the conductor (I) is directly proportional to the potential difference (E) applied to the conductor and is inversely proportional to the resistance (R).

I = E/R

The current is measured in ampere. 

For Example

An ampere may be defined as the current which deposits 0.001118 g of silver in a 15% solution of AgNO, in a voltameter of specified dimensions. 

The unit of electrical resistance in Ohm may be defined as the resistance at 0 degrees C of a column of mercury of length 106.3 cm having weight of 14.4521 g and is represented by the symbol  Ω.

The electromotive force is measured in volts. A volt may be defined as the difference in potential required to send a current of one ampere through one-ohm resistance.

Conductance (C): Reciprocal of the resistance of the conductor. This is a measure of the ease of flow of current through the conductor.

                 i.e.       C = 1/R

units:    Ohm-1  Or Ω-1 also expressed in Siemens (S).
