Question
Which instrument is used to measure electric
current? ÂSolution
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.
