Definition
  1. Noun:
    • A form of voltaic cell once used as a standard for electromotive force: A Clark cell is a specific type of electrochemical cell (a device that produces electrical energy from chemical reactions) that was historically employed as a primary reference standard for measuring electromotive force (EMF), which is the voltage generated by the cell.
Usage Examples
  • Noun:
    • The Clark cell provided a stable voltage reference for early electrical measurements.
    • Scientists calibrated their instruments against a standard Clark cell.
Advanced Usage
  • "Clark standard cell": This is a fuller name emphasizing its role as a calibration standard.
    • The laboratory maintained a Clark standard cell for precise voltage comparisons.
Variants and Related Words
  • Weston cell (n): A later, more stable type of standard cell that largely replaced the Clark cell.
    • The Weston cell became the new international standard for EMF.
Synonyms
  • Standard cell: A general term for an electrochemical cell used as a voltage standard.
  • Voltaic cell: A broader term for any cell that generates electricity through chemical action.
Notes on Meaning
  • The Clark cell is an obsolete technical term from the history of science and electrical engineering. It is named after its inventor, Latimer Clark. Its key characteristic was providing a reproducible and stable voltage (approximately 1.434 volts at 15°C) to calibrate other instruments. It is not a term used in everyday language but appears in historical or specialized technical contexts.
Noun
  1. a form of voltaic cell once used as a standard for electromotive force
