What type of electrical device can be damaged by voltage spikes?

Voltage spikes can potentially damage all types of electrical devices. These spikes, often caused by lightning strikes, power surges, or switching on and off of large electrical loads, can exceed the voltage ratings of various devices, leading to failure or reduced lifespan.

Household appliances, including refrigerators, microwaves, washing machines, and especially sensitive electronics like computers and televisions, can all be affected by sudden changes in voltage. Even outdoor lighting systems can suffer damage. The impact of a voltage spike is not limited to any specific category of devices; thus, the assertion that all household electrical devices can be harmed is accurate. Protecting these devices with surge protectors or voltage regulators is a common preventive measure against such risks.
