Important Questions on Galvanometer and Its Types
A moving coil galvanometer on connecting with a high resistance in series is converted into:

What are the different types of galvanometer.

Draw a neat and labelled diagram of a suspended moving coil galvanometer. Also, show that the current through an is directly proportional to the deflection of a coil.

Why the coil of the moving coil galvanometer is wound over an aluminium frame.

The radial magnetic field is used in a suspended coil galvanometer to provide-

State properties of the material of the wire used for suspension of the coil in a Suspended Coil Galvanometer.

Why the pole piece of the magnet used in a pivoted coil galvanometer are Cylindrical surface of a bar magnet

What is pivoted coil galvanometer

What is the construction of moving coil galvanometer?

Describe the working mechanism of pivoted coil galvanometer.

Why in a moving coil galvanometer, a strong horseshoe magnet of concave shaped pole pieces is used

Write the Types of Galvanometer.

In order to increase the sensitivity of galvanometer,

The thermo e.m.f of the copper-constantan couple is per degree. The smallest temperature difference that can be detected with this couple and a galvanometer of resistance capable of measuring the minimum current of is:

The maximum current in a galvanometer can be . It's resistance is . To convert it into an ammeter of , a resistor should be connected in

When a galvanometer is shunted with a resistance, the deflection is reduced to one-fifth. If the galvanometer is further shunted with a wire, find the ratio of decrease in current to the previous current (the main current remains the same).

Two galvanometers A and B requires and current, respectively to produce the same deflection of division. Then

To verify Ohm's law, a student is provided with a test resistor a high resistance a small resistance two identical galvanometers and and a variable voltage source . The correct circuit to carry out the experiment is:-

Identify the option which indicates the correct method to convert a moving coil galvanometer into an ammeter.

Choose the option which correctly depicts the deflection () on the scale of a moving coil galvanometer.
