How is galvanometer converted into an ammeter?

Verified by Experts

To convert galvanometer into an ammeter, a very small resistance called shunt is to be connected in parallel to the galvanometer.

Potential difference between A + B is given by
`V_(AB)=i_(g)xxG = (i-i_(g))S`
`rArr S=(i_(g))/((i-i_(g)))xxG`
