Galvanometer

The galvanometer is a device to measure electric current.The sensitivity of the galvanometer is the minimum value of current that it can measure.For eg.Galvanometer G₁ has a sensitivity of 100mA in a full scale of 100 divisions .This Implies it measure a minimum of 1mA in1 deflection .

Another galvanometer G₂ has a sensitivity of 50mA in a fulla scale of 100 divisions .This Implies it measure a minimum of  0.5 mA in1 deflection which lesser than G₁.Hence G₂ is more sensitive to current.
