Question

Explain how can a moving coil galvanometer be converted
(i) an ammeter
(ii) a voltmeter of given ranges

Answer 1

(I). A galvanometer can be converted into an ammeter by connecting a low resistance in parallel to the galvanometer.

(II). A galvanometer can be converted into a voltmeter by connecting a very high resistance is connected in series to the galvanometer. The voltmeter is always connected in parallel to a circuit.
