Sensitivity and Accuracy of Moving Coil Galvanometer

In a moving coil galvanometer, when the number of turns of the coil is doubled,

The current sensitivity of a moving coil galvanometer increases by $20\%$ when its resistance is doubled. Calculate, by what factor does the voltage sensitivity change?

How do you find the resistance of a wire using a meter bridge?

What is balance point in Kelvin's method of determination of galvanometer resistance Shaalaa?

What is the use of Kelvin's method?

What is the use of Kelvin's method?

What will happen if a high resistor is connected in parallel with the galvanometer while converting it into a voltmeter?

Why a high-value resistor is used in series with a galvanometer in order to convert it into a voltmeter?

To convert a galvanometer into a _____ a high resistance must be connected in series with it.

To convert a galvanometer into a voltmeter a high value resistor is connected in parallel with it.

A resistance of $900\mathrm{\Omega }$ is connected in series with a galvanometer of resistance $100\mathrm{\Omega }$. A potential difference of $1\mathrm{V}$ produces $300$ division deflection in the galvanometer. The value of figure of merit will be

The figure of merit of a galvanometer is defined as
