What is the purpose of a surge protector in an electronic setup?

The purpose of a surge protector in an electronic setup is to protect electronic devices from sudden voltage spikes or surges. When there is a sudden increase in voltage, such as from a lightning strike, power outage, or other electrical issues, a surge protector acts as a barrier to divert or limit the excess voltage, preventing it from reaching and damaging the connected devices. By providing a protective barrier, surge protectors help extend the lifespan of electronic equipment and safeguard them against potential damage. This is particularly important for sensitive and expensive devices like computers, televisions, gaming consoles, and other electronics.
