Answer 1

The electric potential difference is the electric potential energy per unit charge

Explanation:

First of all, we define the concept of electric potential. The electric potential is a measure of the gradient of the electric field at a certain point of the space. The electric potential at a distance $r$ from a positive charge of magnitude $q$ is given by

$V(r) = \frac{kq}{r}$

where k is the Coulomb's constant.

Now we can define the electric potential energy and the electric potential difference:

• Electric potential energy is the energy possessed by a charge due to the presence of an electric field. For a charge of magnitude $q$ immersed in an electric field, its potential energy is given by $U=qV$, where V is the electric potential at the location of the charge.
• The electric potential difference is simply the difference in electric potential between two points in the space. For instance, if the potential at point A is V(A) and the potential at point B is V(B), then the potential difference is $\Delta V = V(A)-V(B)$

The electric potential energy is also defined as the work done on a charge q moved through a potential difference of $\Delta V$. Consequently, the potential difference $\Delta V$ represents the work per unit charge done, i.e. the work done when moving a unitary charge through a potential difference $\Delta V$.
