A load is supplied by a 230 V, 50 Hz. The active power P and the reactive power Q consumed by the load such that 1 kW ≤ P ≤ 2 kW and 1 kVAR ≤ Q ≤ 2 kVAR. A capacitor connected across the load for power factor correction generates 1 kVAR reactive power. The worst case power factor after power correction is
