1. The document discusses power factor correction by adding a capacitor to an existing load to make the power factor closer to 1. 2. It provides equations to calculate the current drawn by the original load, the supply current after adding a capacitor, and the current drawn by the capacitor. 3. As an example, it calculates the current values for a 2 kW mud pump with an original power factor of 0.5 that is corrected to 0.95 by adding a capacitor, and draws a phasor diagram to illustrate the current values and phase angles.
