A non-inductive load takes a current of 15A at 125V. An inductor is then connected in series in order that the same current shall be supplied from 240V, 50Hz mains. Ignore the resistance of the inductor and calculate the inductance of the inductor
Answers: 3
, which is the resistance to the flow of current through the inductor.
