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
Correct Answer: Option D
Explanation
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 = 30/0 = 10.0
