Question

When the number of turns in a moving coil galvanometer is doubled, what happens to its voltage sensitivity?

Answer 1

1. The deflection caused in the galvanometer coil when a unit potential difference is applied across it, is known as voltage sensitivity.
2. We can say that the voltage sensitivity is directly proportional to the number of turns in a coil.
3. When the number of turns in a coil in a moving coil galvanometer is doubled, the voltage sensitivity of the galvanometer also gets doubled.
