How does voltage sensitivity of a galvanometer will change as number of turns of its coil are doubled? |
Halved Doubled Remains same Insufficient information |
Remains same |
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. |
