To convert a galvanometer into an ammeter, one needs to connect a

1. low resistance in parallel
2. high resistance in parallel
3. low resistance in series
4. high resistance in series

Correct answer: low resistance in parallel

Solution

To convert a galvanometer into an ammeter, a low resistance (shunt) is connected in parallel to allow most of the current to bypass the galvanometer, protecting it from high currents.
