Class 12PhysicsMoving Charges and MagnetismThe Moving Coil Galvanometer (Sensitivity) and Ammeter and Voltmeter Conversion
MediumWhat is a galvanometer? Give its applications.
(N/A) galvanometer is an electromechanical instrument used for detecting and indicating an electric current.
It works on the principle that a current-carrying coil placed in a magnetic field experiences a magnetic torque.
Applications:
$1$. It is used to detect the presence of small electric currents in a circuit.
$2$. By connecting a low resistance (shunt) in parallel,it can be converted into an ammeter to measure current.
$3$. By connecting a high resistance in series,it can be converted into a voltmeter to measure potential difference.
$4$. It is widely used in laboratory experiments and sensitive electronic measuring instruments.

$A$ moving coil galvanometer is converted into an ammeter reading up to $0.03\,A$ by connecting a shunt of resistance $4r$ across it,and into an ammeter reading up to $0.06\,A$ when a shunt of resistance $r$ is connected across it. What is the maximum current which can be sent through this galvanometer if no shunt is used?
