Question

The range of an ammeter of resistance 'g' can be increased from 'i' to 'ni' by connecting

Answer 1

Answer:

So decreasing the ammeter range is practically not possible. To increase the range of ammeter, you need to connect a shunt resistance in parallel to the branch where you want to measure the current. The ratio of resistances connected is multiplied by the shown value of ammeter to obtain the original value.
