Calculate the scale position is radians for a current of 4 amperes




The inductance of a certain moving iron ammeter is (8 + 4? – 1/2?)2 µH where 0 is he deflection in radians from the zero position. The control spring torque is 12 x 10-6 N-m per radians. Calculate the scale position is radians for a current of 4 amperes.
