Question

What is the use of potential and potential difference in our day to day life?

Answer 1

The use of potential and potential difference is in electronic appliances for the flow of current. When two charged bodies at different potentials (i.e if there is a potential difference) are connected by a metal wire, then charges will flow from the body at higher potential to the one at lower potential (till they both acquire the same potential). This flow of charges in the metal wire constitutes an electric current. Thus, it is the potential difference which makes the current to flow.
