Formula Used in “Electric Potential Calculator”
The electric potential (V) at a point in space due to a point charge can be calculated using the standard formula:
V = frac{k cdot Q}{r}
Where:
- V = Electric potential (in volts, V)
- k = Coulomb’s constant, approximately 8.99 times 10^9 , N cdot m^2/C^2
- Q = Magnitude of the point charge (in coulombs, C)
- r = Distance from the charge to the point where the potential is being calculated (in meters, m)
Step-by-Step Breakdown of the Formula
- Identify the point charge (Q): Determine the magnitude of the charge, typically expressed in coulombs (C).
- Measure the distance (r): Find the distance from the charge to the point where you want to calculate the electric potential, in meters (m).
- Substitute values into the formula: Plug the values of Q and r into the formula using the calculated constant k.
- Compute the electric potential (V): Use the equation to find the value of the electric potential in volts (V).
Example Calculation
Let’s consider a scenario where we want to calculate the electric potential created by a point charge of +5 μC (microcoulombs) at a distance of 0.1 m from the charge.
| Variable | Symbol | Value |
|---|---|---|
| Point charge | Q | 5 μC = 5 × 10-6 C |
| Distance from charge | r | 0.1 m |
| Coulomb’s constant | k | 8.99 × 109 N·m2/C2 |
Now, substituting the values into the formula:
V = frac{(8.99 times 10^9 , N cdot m^2/C^2) cdot (5 times 10^{-6} , C)}{0.1 , m}
Calculating gives:
V = frac{44.95 times 10^3}{0.1} = 449500 , V
This means that the electric potential at a distance of 0.1 m from a +5 μC charge is approximately 449,500 volts.

Understanding the Input Fields
Below are the essential input fields you will encounter when using the calculator:
- Charge (Q): This field requires the charge value, measured in coulombs (C). The electric potential is proportional to the amount of charge; thus, a larger charge results in a higher electric potential.
- Distance (r): This input represents the distance from the charge to the point of interest, measured in meters (m). Electric potential decreases with increased distance.
- Units: Select between SI (standard international) and CGS (centimeter-gram-second) systems. Consistent units ensure the formula’s application is accurate and avoids potential errors.
Examples:
If you input a charge of 1 microcoulomb (1 x 10-6 C) and a distance of 2 meters, the calculator will use these values to compute the electric potential. Ensure the values are correctly formatted, e.g., inputting 0.001 instead of 1 mC.
How to Interpret the Results
Once the calculation is complete, the output will present the electric potential (V) value, typically in volts (V).
- Understanding Electric Potential: The electric potential indicates the amount of work needed to move a positive charge from a reference point (usually at infinity) to a specific point in the field of the source charge.
- Common Errors:
- Ensure the charge is entered correctly, whether in microcoulombs, nanocoulombs, etc. For instance, enter 10 microcoulombs as 1.0E-5.
- Check the distance input. Quantities must be correctly indicated in meters for accurate results.
- Watch out for unit mismatches. Always choose the same system (SI or CGS) to avoid discrepancies in results.
