A moving coil galvanometer has a full-scale deflection of 3A equivalent to 30o deflection. The sensitivity of the instrument is
A
33.0
B
0.1
C
90.0
D
10.0
Verified Correct Answer: D.
Physical Principles & Numerical Solution
The sensitivity of a measuring instrument is given by deflection per unit current: and given that deflection = 30º; and current (I) = 3A: then the sensitivity of the meter = 30/3 = 10.0
