A moving coil galvanometer on connecting with a high resistance in series is converted into:

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

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

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

To convert a galvanometer into a voltmeter, a low resistance should be connected in series.

In ballistic galvanometer, the frame on which the coil is wound is non-metallic to:

In order to increase the sensitivity of galvanometer,

The maximum current in a galvanometer can be $10 \mathrm{mA}$. It's resistance is $10\mathrm{\Omega }$. To convert it into an ammeter of $1 \mathrm{A}$, a resistor should be connected in

When a galvanometer is shunted with a $4 \mathrm{\Omega }$ resistance, the deflection is reduced to one-fifth. If the galvanometer is further shunted with a $2 \mathrm{\Omega }$ wire, find the ratio of decrease in current to the previous current (the main current remains the same).

Two galvanometers A and B requires $2 \mathrm{mA}$ and $3 \mathrm{mA}$ current, respectively to produce the same deflection of $10$ division. Then

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

If the galvanometer current is 10mA, resistance of the galvanometer is $40\mathrm{ }\mathrm{\Omega }$ and shunt $2\mathrm{\Omega }$ is connected to the galvanometer, what should be the maximum current which can be measured by this ammeter ?
