(N/A) galvanometer is an electromechanical instrument used for detecting and indicating an electric current. Its primary uses are:
$1$. Detection of Current: It is used to detect the presence of a small electric current in a circuit.
$2$. Conversion to Ammeter: By connecting a low resistance (shunt) in parallel with the galvanometer,it can be converted into an ammeter to measure the magnitude of current in a circuit.
$3$. Conversion to Voltmeter: By connecting a high resistance in series with the galvanometer,it can be converted into a voltmeter to measure the potential difference between two points in a circuit.
