Question

A shunt of resistance 1 Ω is connected across a galvanometer of 120 Ω resistance. A current of 5.5 ampere gives full scale deflection in the galvanometer. The current that will give full scale deflection in the absence of the shunt is nearly :

TestHub · Accepted Answer

The current that will given full scale deflection in the absence of the shunt is nearly equal to the current through the galvanometer when shunt is connected i.e. I g ​ As I g ​ = G + S I S ​ = 120 + 1 5.5 × 1 ​ = 0.045 ampere
