Solution
D.
The electric and the magnetic field, associated with an electromagnetic wave, propagating along the +z - axis, can be represented by
D.
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 T
R2 = 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.
