To convert a moving coil galvanometer into an ammeter, one needs to connect a

An ammeter should have very low resistance, so that it may

If galvanometer is shunted by $\frac{1}{n^{\mathrm{th}}}$ of its value, then what fraction of the current passes through the galvanometer?

The range of an ammeter of resistance $G$, is increased from $I$ to $nI$. This can be done by connecting

The range of voltmeter can be increased by

For the measurement of potential difference, voltmeter is connected

A voltmeter of resistance $G \mathrm{ohm}$ has range $V \mathrm{volt}$. To increase its range upto ($nV$), one must connect

Assertion: The voltmeter is a low resistance galvanometer.

Reason: The potential difference is measured across a resistance.
