Question

    Which instrument is used to measure electric

    current?  
    A Voltmeter Correct Answer Incorrect Answer
    B Ammeter Correct Answer Incorrect Answer
    C Galvanometer Correct Answer Incorrect Answer
    D Ohmmeter Correct Answer Incorrect Answer

    Solution

    An ammeter measures the current in a circuit and is always connected in series.   It has very low resistance to ensure the circuit current remains unaffected.   Unlike a voltmeter (which measures potential difference), ammeters show current in amperes.   They are common in school labs and industries.
