QUESTION #2 Moving Coil Galvanometer
In a moving coil galvanometer, two moving coils M₁ and M₂ have the following particulars: aligned R₁ &= 5 Ω, N₁ = 15, A₁ = 3.6 × 10⁻³ m², B₁ = 0.25 T R₂ &= 7 Ω, N₂ = 21, A₂ = 1.8 × 10⁻³ m², B₂ = 0.50 T aligned Assuming that torsional constant of the springs are same for both coils, what will be the ratio of voltage sensitivity of M₁ and M₂ ?
