The inductance of a certain moving-iron ammeter is expressed as L= 10+ 30 – (& /4) µH, where e is the deflection in radians from the zero position. The control spring torque is 25 x 10° Nm/radian. The deflection of the pointer in radian when the meter carries a current of 5 A, is (A) 2.4 (С) 1.2 (В) 2.0 (D) 1.0
