Calculates the electric potential (voltage) at a point due to one or more point charges or in a uniform electric field.
Start with your values, or try a preset.
Enter Charge 1 (Coulombs), Distance to Charge 1 (meters), Charge 2 (Coulombs), Distance to Charge 2 (meters), Electric Field Strength (V/m), and Distance in Electric Field (meters) in the units shown.
Read Potential due to Electric Field, Potential due to Charge 2, Potential due to Charge 1, and Total Electric Potential in the results panel. Results update as you change the inputs.
Choose a preset to load an example, then adjust the values for your situation.
