Question:

How does voltage sensitivity of a galvanometer will change as number of turns of its coil are doubled?

Options:

Halved

Doubled

Remains same

Insufficient information

Explanation:

The correct answer is option (3) : Remains same

$\frac{\phi}{V}=\frac{NBA}{R}$

As number of tums is doubled, Resistance R will also get doubled. Hence voltage sensitivity remains same.
