What is the primary function of a surge protector?

The primary function of a surge protector is to safeguard electronic equipment from voltage spikes. When there is a sudden surge in electrical current, such as during a thunderstorm or power fluctuation, it can cause significant damage to sensitive electronics. A surge protector works by diverting excess voltage away from the devices connected to it, thereby protecting them from potential damage caused by these spikes.

In the context of electrical safety, this is an essential component for ensuring the lifespan and functionality of devices like computers, televisions, and other sensitive electronics. The other options, while related to electronic devices, address different functions; boosting internet speed, providing additional outlets, or enhancing wireless connections are not the primary role of surge protectors.
