Question

Current sensitivitey of moving coil depend upon :-

A. number of turn

B. magnetic field

C. area

D. all of these​

Answer 1

Answer:

D. All of these

HOPE THIS HELPS

Answer 2

Answer:

Sensitivity of a moving coil galvanometer is defined as the current  i  in microampere required to consume 1 millideflection.

∴   Sensitivity      k=  

i

θ

​  

=  

C

NBA

​  

 

where all the symbols have their usual meaning and C is the torque per unit twist

Thus the sensitivity of the galvanometer can be increased either by increasing the number of turns (N), using strong magnet or increasing the area of the coil  (A)
