The series R–L–C load in the figure is supplied from 230 V, 50 Hz. Before the capacitor C_{p} is connected, determine (a) the current I drawn by the load (answer in A) and (b) the power factor of the load. (c) Find the capacitance C_{p} that must be connected across the supply terminals, as shown, to raise the overall power factor to 0.95 lagging (answer in μF).
