Question

Current moves from high to low potential and potential acts as pressure i.e. from high to low. But the definition of potential is very different. Explain ?

Answer 1

Dear student

The concept of electric potential is used to express the effect of an electric field of a source in terms of the location within the electric field.
A test charge with twice the quantity of charge would possess twice the potential energy at a given location; yet its electric potential at that location would be the same as any other test charge.
A positive test charge would be at a high electric potential when held close to a positive source charge and at a lower electric potential when held further away. In this sense, electric potential becomes simply a property of the location within an electric field.
