Q. No.When will the current sensitivity of a moving coil galvanometer be high?
(\(N=\) number of turns, \(B=\) magnetic field, \(A=\) area of coil, and \(C=\) Torsional constant of spring)
(\(N=\) number of turns, \(B=\) magnetic field, \(A=\) area of coil, and \(C=\) Torsional constant of spring)
| 1. | \(N\) is small | 2. | \(B\) is small |
| 3. | \(A\) is small | 4. | \(C\) is small |
