The negative sign shows that the potential at the point f in the figure is lower than that at point i. Therefore, the potential always decreases along a path that extends in the direction of the electric field lines.
Calculating the Potential from the Field
This is the same result as we obtained in (a), as it must be; the potential difference between two points does not depend on the path connecting them. Moral: When you want to find the potential difference between two points by moving a test charge between them, you can save time and work by choosing a path that simplifies the use of Equation.
