Electric Potential Distribution Around a Circular Electrode - Simulation Visualization #1896626 (License: Personal Use)

This simulation depicts the 2D electrostatic potential field φ(x, y) generated by a grounded or negatively biased circular electrode embedded in a uniform medium. The color gradient-ranging from red (0 V) to deep blue (-100 V)-illustrates how potential decays radially outward, with equipotential lines forming smooth curves distorted near the electrode boundary. White markers outline the electrode perimeter, indicating discrete boundary points used in the numerical solver.

Used in academic and engineering contexts for teaching electrostatics, validating finite element method (FEM) solvers, or designing microelectrodes in lab-on-chip devices; targets students, researchers, and simulation engineers seeking visual intuition of field behavior.
