An ammeter requires a change of 3 A in its coil to produce a change in deflection of the pointer by 12 mm. Its sensitivity is
4 mm/A
Summarizing the Calculation Quantity Value Unit Change in Current (\Delta I) 3 A Change in Deflection (\Delta \theta) 12 mm Sensitivity (S = (\Delta \theta)/(\Delta I)) (12)/(3) = 4 mm/A Therefore, the sensitivity of the ammeter is 4 mm/A.
Important Questions from Sensitivity
If meter A requires 100 mA to give full-scale deflection, meter B requires 50 mA to give scale deflection and meter C requires 80 mA to give full-scale deflection, then the

a. An automatic washing machine
b. An automatic intensity adjustable light bulb
Which of these systems will be more sensitive to the variation in system's gain?
