Q.
A galvanometer has a resistance of
60
Ω
and has
50
divisions. A current of
1
m
A
is passed and it gives full-scale deflection. When shunt of
2.5
Ω
is connected in parallel with the galvanometer, the deflection reduces, to
10
divisions for the same current. Find the maximum current that can be measured with the galvanometer converted into an ammeter.
