The electric potential VV due to a system of point charges is given by the equation V=14πε0∑iqiriV=\frac{1}{4 \pi \varepsilon_{0}} \sum_{i} \frac{q_{i}}{r_{i}}. According to the principle of superposition, the summation term represents which of the following?

A

The algebraic sum of individual potentials from each point charge

B

The vector sum of electric fields from each point charge

C

The average potential contribution from all point charges

D

The product of charge magnitudes and their respective distances
