Electrostatic Potential due to Point Charge Calculator

Formula

The formula to calculate the Electrostatic Potential (V) is:

\[ V = \frac{[Coulomb] \cdot Qpt}{r} \]

Where:

\(V\) is the Electrostatic Potential (measured in Volts).
\([Coulomb]\) is the Coulomb constant, approximately \(8.9875 \times 10^9 \, \text{N m}^2/\text{C}^2\).
\(Qpt\) is the Point Charge (measured in Coulombs).
\(r\) is the Separation between Charges (measured in Meters).

Definition

Electrostatic Potential is the potential energy per unit charge at a point in an electric field, measured relative to a reference point.

Point Charge is a small localized object or particle that has an electric charge, and is a fundamental concept in understanding electrostatic forces and interactions.

Separation between Charges is the distance between two point charges in an electrostatic field, affecting the electrostatic force between them.

How to calculate Electrostatic Potential

Let's assume the following values:

Point Charge (Qpt) = 0.000012 Coulombs
Separation between Charges (r) = 2119.850 Meters

Using the formula:

\[ V = \frac{8.9875 \times 10^9 \cdot 0.000012}{2119.850} \]

Evaluating:

\[ V \approx 50.029 \]

The Electrostatic Potential is approximately 50.029 Volts.
