If the number of turns in the coil of a moving coil galvanometer decreases, the resistance of the galvanometer, (a) decreases (b) increases (c) remains the same (d) may increase or decrease

Answer: (a). Coil resistance R = /A, and wire length L is proportional to the number of turns. Fewer turns means a shorter wire, so the resistance decreases. So the answer is (a) decreases.

Moving Coil Galvanometer, Ammeter & Voltmeter

If the number of turns in the coil of a moving coil galvanometer decreases, the resistance of the galvanometer,

Show answer and solution

Answer: (a)

Coil resistance $R = \rho\frac{L}{A}$ , and wire length $L$ is proportional to the number of turns.
Fewer turns means a shorter wire, so the resistance decreases.
So the answer is (a) decreases.
