Surge protectors protect electronic equipment against a surge of electricity, which can be caused by a lightning strike or another electrical issue. By plugging electronics, such as a computer or a television, into a surge protector, one can stop the surge of electricity from frying the device.
The life of a surge protector is determined by a few factors. The quality of the surge protector will determine how long it can last, as well as the electrical load that it can handle. A buzzing sound or indicator light on the surge protector will indicate when it has reached the end of its life.Learn more about Computers & Hardware
