Two moving coil galvanometers. X and Y have coils with resistances 10 Ω and 14 Ω, cross-sectional areas 4.8 × 10−3m2 and 2.4 × 10−3m2 , number of turns 30 and 45 respectively. They are placed in magnetic fields of 0.25 T and 0.50 T respectively. Then the ratio of their current sensitivities and the ratio of their voltage sensitivities are respectively.
