(i) A coil which has 6Ω resistance and 25.5mH inductance is energized from a 400V, 50Hz supply. Calculate the current.
(ii)A capacitor is then connected in parallel with the coil so that the overall power factor is unity. Calculate the capacitance of the capacitor.
(iii) What current will be flowing in the main supply cable when the capacitor is connected in the circuit and what is the capacitor current?
