A load consists of a resistance R in parallel with a capacitor of reactance X. The load is fed from a single phase supply through a line of impedance 8.4 + j11.2 ohms. The rms voltage at the load terminal is 1200 at 0 degress V rms, and the load is taking 30 kVA at 0.8 power factor leading. a) find values of R and X. b)Determine the supply voltage V.
