Answer:
Surge protection, is the right answer.
Explanation:
A surge protector is a device invented to protect the electrical appliances from voltage spikes. And the protection given by this device to the electrical appliances is called surge protection. A surge protector helps us to check the degradation of internal microprocessors in our electronic appliances. At the time when the voltage approaches a high point, surge protectors re-route the additional voltage with the help of a pressure-sensitive valve and thus provide protection to our devices.
