The galvanometer cannot as such be used as an ammeter to measure the value of current in a given circuit. The following reasons are
I. galvanometer gives full scale deflection for a small current.
II. galvanometer has a large resistance.
- III. a linear scale cannot be designed so that \( I \propto \phi \).
IV. a galvanometer can give inaccurate values.
(a) I and IV
(b) II and III
(c) I and II
(d) III and IV
