**Problem 8: The full scale deflection for a galvanometer is 10 mA. Its resistance is 100 Ω. How it can be converted into an ammeter of range 100 A.**

**Solution**

Given data I_{g} = 10 mA R_{g} = 100 ohm I = 100 A

Required R_{s} =?

**Strategy:** The ratio of the shunt resistance to galvanometer resistance is given by

Put the values
