With the help of a circuit expain the function of a shunt used in a galvanometer.

With the help of a circuit diagram explain the function of a shunt used in a galvanometer.

If a galvanometer is converted into an ammeter by using a shunt, determine the relation between the ammeter current and the galvanometer current with the help of a circuit diagram. What kind of galvanometer is used for this ?

With the help of a labelled diagram, explain the principle and working of a moving coil galvanometer.

Draw a circuit diagram showing the use of an ammeter and a voltmeter.

Discuss the difference between ammeter and voltmeter. Draw a circuit diagram indicating how they may be used? How a galvanometer can be converted to an ammeter and voltmeter?

The resistances of a galvanometer is 200 Omega and full-scale deflection is obtained for a current of 5mA. The galvanometer is connected with a source of electricity through a resistance of 58 Omega in series. The emf of the cell is 30V and its internal resistance is negligibly small .Find out the resistance of the shunt that should be connected with the galvanometer in parallel.

Why is phosphor-bronze used as the material of the suspension-thread in a suspended coil galvanometer?

State Ampere's circuital law. With the help of this law determine the magnetic field at an internal point of a long solenoid.
