It is proposed to use a non-inductive shunt to increase the range of a 10A moving iron-ammeter to 100A. The resistance of the instrument, including the leads to the shunt, is 0.06 ohms and the Inductance is 15 × 10^-6 H at full scale. If the combination is correct on a d.c circuit, find the error at full scale on a 50 Hz a.c circuit.

It is proposed to use a non-inductive shunt to increase the range of a 10-A moving iron ammeter to 100 A. The resistance of the instrument, including the leads to the shunt, is 0.06 Ω and the inductance is 15 μH at full scale. If the combination is correct on a.d.c circuit, find the error at full scale on a 50 Hz a.c. circuit
