Vedclass · Answer

(D) The resistance $R$ of a wire is given by the formula $R = \rho \frac{L}{A}$,where $\rho$ is the resistivity,$L$ is the length of the wire,and $A$ is the cross-sectional area.Since the coil of a galvanometer is made of a wire of a certain length,the total length $L$ is directly proportional to the number of turns $N$ $(L \propto N)$.If the number of turns $N$ is decreased,the total length $L$ of the wire used in the coil decreases.Since $R \propto L$,a decrease in the length $L$ leads to a decrease in the resistance $R$ of the galvanometer.

If the number of turns in the coil of a galvanometer is decreased,then the resistance of the galvanometer:
