In this video, the concept of Electric Potential (V) is discussed, which is described as an abstract
numerical value associated with points in space. It is explained that Electric Potential is different from
Electric Potential Energy, although they are related. The video highlights that Electric Potential is a way to
determine the Electric Potential Energy for a charge placed at a specific point in space with a given
Electric Potential value. The formula for Electric Potential is provided as V = kQ/r, where k is the electric
constant, Q is the charge creating the Electric Potential, and r is the distance between the charge and the
point in space. The units of Electric Potential are Joules per Coulomb, indicating its connection to energy.
The relationship between Electric Potential and Voltage is also touched upon, with Voltage referring to
the difference in Electric Potential between two points in space.
