Question

(b) The coil area of a galvanometer is \( 1.6 \times 10^{4} m ^{2} \). It consists of 200 turns of a wire and is in a magnetic field of \( 0.2 T \). The restoring torque constant of the suspension fibre is \( 10^{-6} Nm \) per degree. Calculate the maximum current that can be measured by the galvanometer. If the scale can accomodate \( 30^{\circ} \) deflection.
