$A$ voltmeter has a resistance of $G \, \Omega$ and a range of $V \, \text{volts}$. The value of the resistance that must be connected in series to convert it into a voltmeter of range $nV \, \text{volts}$ is:

The galvanometer has a resistance of $1.8 \Omega$. Calculate the value of shunt to increase the range of galvanometer by $10$ times. (in $\Omega$)

$A$ voltmeter of resistance $1000\,\Omega$ gives full scale deflection when a current of $100\,mA$ flows through it. The shunt resistance required across it to enable it to be used as an ammeter reading $1\,A$ at full scale deflection is ............... $\Omega$.

The resistance of an ideal voltmeter is . . . . . . .

In a suspended-type moving coil galvanometer,a quartz suspension is used because:

In the conversion of a moving coil galvanometer into an ammeter of a required range,what is the resistance of the ammeter so formed? [$S$ = shunt resistance and $G$ = resistance of the galvanometer]
