The sensitivity of a moving coil galvanometer depends on OR In order to increase the sensitivity of a moving coil galvanometer, one should decrease
1 angle of deflection
2 earth's magnetic field
3 torsional constant of the spring
4 none of these
Explanation:
C Current Sensitivity $=\frac{\mathrm{nBA}}{\mathrm{k}}$ Where, $\mathrm{k}=$ Constant torsional rigidity. $\mathrm{n}=$ Number of turns in the coil $\mathrm{A}=$ Area of coil $\mathrm{B}=$ Magnetic field in which coil rotator

The resistance of galvanometer is $50 \Omega$ When 0.01 A current flows in it, full scale deflection is obtained in galvanometer, the resistance of shunt connected to convert galvanometer into an ammeter of range $5 \mathrm{~A}$, will be

A stray magnetic field does 'NOT' affect the deflection of moving coil galvanometer because
1 magnetic field inside galvanometer is zero
2 magnetic field inside galvanometer is very strong
3 magnetic field is equal to earth's magnetic field
4 magnetic field inside galvanometer is very weak
Explanation:
B In moving coil galvanometer, the coil is suspended in a very strong uniform magnetic field by two magnetic pole piece. The earth's magnetic field is weak as compared to magnetic field. Therefore, it does not effect the working of magnetic field.
