Moving Coil Galvanometer, Ammeter, and Voltmeter

  • Moving Coil Galvanometer:

    • Device used to detect current in a circuit
    • Consists of a coil placed in a magnetic field
    • When current flows through the coil, it experiences a torque
  • Ammeter:

    • Device used to measure current in a circuit
    • Connected in series with the circuit
    • Low resistance to ensure minimal voltage drop
  • Voltmeter:

    • Device used to measure potential difference across a component
    • Connected in parallel with the component
    • High resistance to prevent significant current flow
