An iron anode and copper cathode share an electrolyte. Follow electrons through the external metallic path, ionic conduction in solution, and the charge balance that determines iron loss.
• 3D scene parts: iron anode; copper cathode; electrolyte and ionic path; metallic connection and switch; ammeter and accumulated loss. • Controls: driving potential (0.1–0.8 V), total circuit resistance (100–1000 Ω), exposed iron area (10–100 cm²), metallic connection closed. • Live readouts: galvanic current; passed charge; dissolved iron; uniform penetration estimate; anodic current density; physical elapsed time. • Guided experiments: Open external path; Lower circuit resistance; Smaller anode area. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.
I=ΔV/R Q=I t; iron mass=Q×55.845/(2×96485) grams Depth=m/(7.87 A) cm; 1 cm=10⁴ µm One animation second = one hour of physical exposure.
Constant-potential, lumped-resistance galvanic circuit; 100% iron dissolution efficiency and uniform loss. No polarization curves, passivation, oxygen diffusion, pitting or self-corrosion. The thickness display is exaggerated and does not change the imposed circuit current. Try the preset experiments, then compare the live readouts with the equations.
No, ions carry solution current. Electron flow is on the metallic circuit.
No. Self-corrosion mechanisms are outside this circuit model.
