A moving coil galvanometer consists of a coil of N turns are area A suspended by a thin phosphor bronze strip in radial magnetic field B. The moment of inertia of the coil about the axis of rotation is l and c is the torsional constant of the phosphor bronze strip. When a current i is passed through the coil, it deffects through an angle `theta` Magnitude of the torque experienced by the coil is independent of
