The question pertains to the working of electromagnetic cells in which a redux reaction results in movement of the electrons which manifest itself as electrical energy.
00:14
When a metal is placed in a solution of its ion, the metal occurs either a positive or negative charge with respect to the solution.
00:22
This positive or negative charge comes due to reduction or oxidation reaction respectively.
00:29
When excitation takes place, metal atoms from the electrode move into the solution as metal ions and electrons are left on the electrode.
00:38
This imports a negative charge on the electrode.
00:41
Also, the metal ions can deposit on the surface of this electrode to take up the electron and thus import a positive charge on the electrode.
00:50
On account of this, a definite potential difference is developed between the metal and the solution.
00:57
This potential difference is called the electrode potential.
01:01
The magnitude of the electrode potential of this metal is measure of its relative tendency to lose or gain electrons.
01:10
That is, it is a measure of the relative tendency to undergo oxidation or reduction.

The electromagnetic forces the maximum potential difference between two electrodes of a galvanic or voltaic cell...
