A mathematical model that describes the potential and activity distribution along a wire undergoing anodic dissolution in acidic media is developed in order to account for the spatiotemporal patterns observed with a nickel wire in sulfuric acid. The model simulates the antiphase oscillations observed under galvanostatic conditions and the travelling waves observed when a small external resistor is incorporated in the circuit. The simulations demonstrate the change in pattern as the external resistor is varied.
