Q11 of 54 Page 276

A tangent galvanometer is connected directly to an ideal battery. If the number of turns in the coil is double, the deflection will

We know that for a tangent galvanometer, the relation connecting current, i and the deflection, θ is,



Or,



Where k is the reduction constant and is fixed for a galvanometer.


So, we can see that deflection depends only on i and k. Hence, the deflection won’t change when the number of turns is changed.
