The current sensitivity of moving coil galvanometer is increased by 
. This increase is achieved only by changing in the number of turns of coils and area of cross section of the wire while keeping the resistance of galvanometer coil constant. The percentage change in the voltage sensitivity will be:
A
B
C
Zero
D
Text Solution
Verified by ExpertsThe correct answer is:
A
, If 
(galvanometer resistance) is constant, then 
so percentage change in 
is also 
.
