Question

Define potential difference between two points in electric field?derive an expression for it

Answer 1

Potential difference may be defined as the difference between two point charges. Answer: the work done is carrying a unit positive charge from one point to the other against the electric field intensity is called electric potential ......mm.

Answer 2

Answer:

In electromagnetism, we use a positive charge to define electric fields. Electric potential difference is the difference in electric potential between two points in space. That's really all it is. It is also measured in Joules per coulomb, but this is usually shortened to a different unit: volts.
