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.
Given data Ig = 10 mA Rg = 100 ohm I = 100 A
Required Rs =?
Strategy: The ratio of the shunt resistance to galvanometer resistance is given by
Put the values
