If the number of turns in the coil of a moving coil galvanometer decreases, the resistance of the galvanometer,

When a galvanometer is shunted by a resistance $S$,its current capacity increases $n$ times. If the same galvanometer is shunted by another resistance $S^{\prime}$,its current capacity increases to $n^{\prime}$. The value of $n^{\prime}$ in terms of $n, S$ and $S^{\prime}$ is

If an ammeter is to be used in place of a galvanometer,then we must connect:

$A$ galvanometer of resistance $50\, \Omega$ is connected to a battery of $3\, V$ along with a resistance of $2950\, \Omega$ in series. $A$ full-scale deflection of $30$ divisions is obtained in the galvanometer. In order to reduce this deflection to $20$ divisions,the resistance in series should be.......$\Omega$

What is the value of resistance to double the value of number of turns of coil for a galvanometer? Why?

In a moving coil galvanometer,to make the field radial,what is done?
