Ammeter and Voltmeter


  1. Ammeters are measuring instrument used to measure electric current.
  2. Voltmeters are measuring instrument used to measure potential difference (voltage).
  3. In SPM syllabus, you need to know
    1. how to take reading from ammeter and voltmeter
    2. how to identify the sensitivity of an ammeter and voltmeter.
    3. the connection of ammeter and voltmeter in a circuit.
  4. An ammeter is always connected in series with the load (resistor) in a circuit.
  5. A voltmeter is always connected parallel to the load (resistor) in a circuit.
