Physics Question on Electrical Instruments
The current sensitivity of a moving coil galvanometer depends on
A
the number of turns in the coil
B
moment of inertia of the coil
C
current sent through galvanometer
D
eddy current in Al frame
Answer
the number of turns in the coil
Explanation
Solution
Current sensitivity =KnBA
where K is constant of torsional rigidity.
B is the magnetic field A is coil area.
