Electric Potential Calculator

How to Use the Calculator

1. Enter the charge (Q) in Coulombs. This is the magnitude of the electric charge creating the potential field.
2. Enter the distance (r) from the charge in meters. This is the distance from the charge at which you want to calculate the electric potential.
3. Click the "Calculate" button to compute the electric potential.
4. The result will be displayed in Volts (V).

Understanding Electric Potential

Electric potential (V) at a point in an electric field is the amount of work needed to move a unit positive charge from infinity to that point. It's a scalar quantity measured in Volts (V).

Practical Applications

This calculator is useful for:

• Calculating the electric potential due to point charges in physics problems
• Understanding how charges create electric fields
• Electronics design and analysis
• Particle physics calculations

Example

If you have a charge of 0.0001 Coulombs (100 µC) located 0.5 meters away from a point, the electric potential at that point would be:

V = (9 × 10⁹ N·m²/C²) × (0.0001 C) / 0.5 m = 1,800,000 V = 1.8 MV
