CONCEPT:

  • Voltmeter: The electrical instrument which is used to measure the potential difference between two points in an electric circuit is called a voltmeter.
    • The Voltmeter is connected in parallel in an electric circuit.
  • Galvanometer: It is used to detect the presence of small electric current and voltage. It is connected in series.
  • Fuse: A fuse is a safety device that melts and breaks the circuit when the current exceeds a particular level and thus save the other appliances connected to the circuit.
    • It is connected in series. 
  • Ammeter: The electrical instrument which is used to measure the electric current in an electric circuit is called an ammeter. 
    • An Ammeter is connected in the series combination because the current remains constant in the series combination.
    • This helps in getting an accurate reading from the instruments.

EXPLANATION:

  • Since the potential difference remains constant in the parallel combination. That's why the voltmeter is connected in parallel in an electric circuit. So option 1 is correct.
