Solution


Q.

The deflection in moving coil galvanometer falls from 25 divisions to 5 divisions when a shunt of 24Ω is applied. The resistance of galvanometer coil will be ____    [2024]
1 12Ω  
2 96Ω  
3 48Ω  
4 100Ω  

Ans.

(2)

Let x= current/division.

Without shunt,

After applying shunt,

Now 5x×G=20x×24

G=4×24=96Ω
