A blackout is a temporary loss of electrical power in a specific area. This can happen due to various reasons, such as severe weather, equipment failure, or maintenance work. During a blackout, homes and businesses may lose lighting, heating, and other electrical services, which can disrupt daily activities. Blackouts can vary in duration, from a few minutes to several days. In some cases, emergency services like generators or batteries can provide temporary power. To prepare for a blackout, people are encouraged to have emergency supplies, such as flashlights, food, and water, readily available.
