(i) To measure current we shall connect low resistance R1 in parallel with the coil of moving coil galvanometer. This arrangement is called ammeter.

(ii) To measure potential difference we shall connect high resistance R2 in series with the coil of galvanometer. This arrangement is called voltmeter.
