To improve power factor, capacitors can be added to the circuit. Capacitors store energy in an electric field, and when they are discharged, they provide a current that helps to offset the inductive current caused by motors and other loads. This helps to improve the power factor and reduce energy costs.<\/p>\n<p>Option A is incorrect because a low value of kVAR compared with kW indicates a high power factor, not a low efficiency.<\/p>\n<p>Option C is incorrect because a low value of kVAR compared with kW indicates a high power factor, not unity power factor.<\/p>\n<p>Option D is incorrect because a low value of kVAR compared with kW indicates a high power factor, not maximum load current.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on
