A power outage is a sudden loss of electricity due to factors such as weather conditions, equipment failure, or maintenance work. There are several synonyms that can be used to describe this situation, including blackout, power failure, electrical outage, and power cut. These terms are often used interchangeably and refer to the same disruption in power supply. A blackout typically refers to a complete loss of power in a specific area, while a power failure can refer to a partial or temporary outage. Electrical outage and power cut are more technical terms that describe the interruption in the flow of electricity from the power source to the affected area.
