A galvanometer is converted into an ammeter by connecting
Options
(a) low resistance in parallel
(b) low resistance in series
(c) high resistance in series
(d) high resistance in parallel
Correct Answer:
low resistance in parallel
Explanation:
A galvanometer is converted to an ammeter by connecting a low resistance in parallel so that only a safe fraction of the current passes through the ammeter.
