A current of 200 μA deflects the coil of a moving coil galvanometer through 60 ° . The current to cause deflection through π 10 radian is

Step-by-step solution

In a moving coil galvanometer, the current is related to the angle of deflection by the formula: i ∝ θ . . . 1 From equation (1), it follow sthat i 2 i 1 = θ 2 θ 1 ⇒ i 2 200 μA = π 10 π 3 = 3 10 ⇒ i 2 = 60 μA
