Solution
Yes a galvanometer can be used for measuring the current
Conversion of a galvanometer into an ammeter
A shunt (low resistance) is connected in parallel with a galvanometer.
`S=(I_g/(I-I_g))G`
Here,
I = total current in circuit
G = resistance of the galvanometer
S = resistance of the shunt
Ig = current through the galvanometer
Concept: Moving Coil Galvanometer
