The potential energy and hence, also the electric potential, is only defined up to an additive constant: one must arbitrarily choose a position where the potential energy and the electric potential are zero.

Mar 3, 2025 · To find the voltage due to a combination of point charges, you add the individual voltages as numbers. To find the total electric field, you must add the individual fields as vectors, taking …

This equation gives the change in electric potential energy of a charge q when it moves from position 𝑥 i x i to position 𝑥 f x f in a constant electric field E.

Apr 18, 2025 · Electric potential is constant inside a charged sphere and decreases with distance outside the sphere. Point X makes an equilateral triangle of length r with two equal positive charges …

Dec 24, 2025 · To move the charge from plate A to plate B, an equal and opposite force (F′ = −qE) must be applied. The electric potential—that is, the work W done in moving the positive charge through a …

Basically electric potential is defined as the work done in moving a point charge from one point to another point under a constant electric field, and we find the formula to be V = W / Q V = W /Q.

Jul 23, 2025 · Mathematically, electric potential (V) at a point is defined as the ratio of electric potential energy (U) to the charge (q) at that point: V = U/q. The SI unit of electric potential is the volt (V), …
