A resistor and a capacitor are connected in series with a variable inductor. When the circuit is con- nected to a 240-V, 50-Hz supply, the maximum current given by varying the inductance is 0.5 A. At this current, the voltage across the capacitor is 250 V. Calculate the values of (a) the resistance (b) the capacitance (c) the inductance. [480 Q 6.36 uF: 1.59 HI
