Two moving coil meters, M1 and M2 have the following particulars:R1 = 10 Ω N1 = 30,A1 = 3.6 x 10–3 m2, B1 = 0.25 TR2 = 14 Ω; N2 = 42,A2 = 1.8 x 10–3 m2, B2 = 0.50 T(The spring constants k are identical for the two meters).Determine the ratio of (a) current sensitivity and (b) voltage sensitivity of M2 and M1.
