A resistor and a capacitor are connected in series with a variable inductor. When the circuit is connected to a 550V, 40 hz supply, the maximum current given by varying the inductance is 15 A. At this current, the voltage drop across the capacitor is 2800 V. Calculate the power taken and power factor of the circuit when across a 250 V, 60 Hz source.
