  "id": "MLC-T-CHM-012062",
  "term": "Time constant",
  "field": "Chemistry",
  "definition": "A characteristic parameter representing the time required for a system's response to reach approximately 63.2% of its final value after a step change in input. In electrical circuits, it is often the product of resistance and capacitance (RC) or inductance and resistance (L/R). It quantifies the speed of response or decay in dynamic systems.",
