A power surge is a sudden increase in electrical voltage that can occur in a power line. This spike can happen due to various reasons, such as lightning strikes, downed power lines, or the sudden start of large electrical devices like air conditioners or motors. These surges can last for a fraction of a second but can cause significant damage to electrical appliances and devices. To protect against power surges, many people use surge protectors, which are devices designed to absorb excess voltage and prevent it from reaching connected equipment. Regularly checking the electrical system and using surge protection can help safeguard valuable electronics, such as computers and televisions, from potential harm.
