The correct answer is D. kVAR.
A capacitor is a device that stores electrical energy in an electric field. Capacitors are used in a variety of applications, including power factor correction. Power factor correction is the process of improving the power factor of an electrical system. The power factor is a measure of how efficiently an electrical system is using power. A low power factor indicates that the system is not using power efficiently. Capacitors can be used to improve the power factor of an electrical system by absorbing reactive power. Reactive power is a type of power that does not contribute to the actual work being done by an electrical system. Capacitors can be used to absorb reactive power and improve the power factor of an electrical system.
The kVAR rating of a capacitor is a measure of the amount of reactive power that the capacitor can absorb. The kVAR rating is typically specified on the capacitor’s nameplate. The kVAR rating of a capacitor is important to consider when selecting a capacitor for power factor correction. The kVAR rating of the capacitor should be selected to match the reactive power requirements of the electrical system.
The other options are incorrect. kW is a measure of power. kVA is a measure of apparent power. kV is a measure of voltage.
