The relation between voltage sensitivity ( 
) and current sensitivity 
of a moving coil galvanometer is (Resistance of Galvanometer = G)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
We know in a galvanometer,
Current sensitivity, 
,
where 
is the deflection produced.
Voltage sensitivity, 
But 
as given Gis the resistance of the galvanometer.
Therefore, 
i.e., Voltage sensitivity 
The above relation implies that if current sensitivity increases as well as the resistance increases in same order, the voltage sensitivity will remain unchanged.
