About This Simulation

This interactive visualization demonstrates the electric potential created by a point charge. Adjust the position of point P and the charge value using the sliders, then observe how the test charge moves in the resulting electric field.

The simulation shows:

• The source charge (Q) in red
• The test point (P) in orange
• The test charge's path in green
• Electric field vectors in purple

This tool helps visualize the inverse-square relationship in Coulomb's Law and makes abstract electromagnetic concepts more concrete.
