Answer 2

Explanation:

Given A particular ammeter required, a change  of 2A its coil to  produce a

deflection of the pointer by 5 mm.  Determine its sensitivity and deflection

• So an ammeter requires a change in deflection, so we need to find its sensitivity and deflection factor.  
•    We have Sensitivity = infinitesimal change in output / infinitesimal change in input.
• So sensitivity = Δqo / Δqi
•                        = 5 mm / 2 A
•                         = 2.5 mm / A
• Deflection factor = Δqi / Δqo
•                             = 1 / sensitivity
•                             = 1/2.5
•                             = 0.4 A/mm
