Both are equally sensitive
Data are insufficient to comment
X is more sensitive than Y.
Y is more sensitive than X.
Validate
Solution:
Sensitivity is defined as amount of defection per unit current
S
=
D
1
S
x
=
1
40
MA =
1000
40
= 25Ω/V
S
y
=
1
50
MA =
1000
50
= 20Ω/V
Hence from the above solution, it is clear the sensitivity of x is more then the sensivity of y.
