Question

what is potential difference?
And how potential difference is developed between two half cells by oxidation and reducation and hence generates electricity? Please explain nicely. ​

Answer 1

Answer:

the difference of electrical potential between two points.

Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.

The potential difference is caused by the ability of electrons to flow from one half cell to the other. Electrons are able to move between electrodes because the chemical reaction is a redox reaction. A redox reaction occurs when a certain substance is oxidized, while another is reduced
