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
