  "term": "Differential capacitance",
  "field": "Chemistry",
  "definition": "The derivative of the electric charge on an electrode with respect to the electrode potential, at a constant temperature and pressure. It quantifies the change in charge stored at the electrode-electrolyte interface for a small change in potential. This value is typically measured in farads per square centimeter (F cm⁻²) and provides insight into the structure of the electrical double layer.",
