Question

a)When three inductive loads, each of reactance 9 Ω and resistance 4 Ω are connected in delta which when also connected to a 3-phase supply the loads consume 1.2 kW. Determine the line current and the supply voltage, the phase current and the power factor of the load

b)15 A of current is taken by a non-inductive load at 125 V. In order that the same current shall be generated from 240 V, 50 Hz mains. An inductor is now also then connected in series. Note: The resistance of the inductor should be ignored and also assume the waveform to be sinusoidal. Determine the phase difference between the current and the applied voltage, the impedance of the circuit and the inductance of the inductor.
