This is the same sort of principle that makes water under pressure flow out of a hose -- higher pressure on one end of the hose pushes water toward an area of lower pressure.
You can think of voltage as a measure of electrical pressure. The effect is very similar to applying too much water pressure to a hose. If there is too much water pressure, a hose will burst. Approximately the same thing happens when too much electrical pressure runs through a wire -- the wire "bursts. Even if increased voltage doesn't immediately break your machine, it may put extra strain on the components, wearing them down over time.

Surge Protector. Techopedia Explains Surge Protector. What Does Surge Protector Mean? Techopedia Explains Surge Protector A voltage spike is a short upsurge of voltage intensity that occurs when a surge sustains longer voltage intensity. Surge protector components and features include: An iron core transformer transfers alternating current AC power but cannot absorb sudden surges.
A zener diode protects against common circuit spikes and is sometimes combined with a transient voltage suppression diode. If a circuit breaker is out or blows a fuse, a surge protector provides internal protection and protects against device and exterior surges.
Uninterruptible power supply takes in spikes using a low pass filter and allows external power beyond the battery, which supplies uninterrupted power. A metal oxide varistor MOV is thermal fused and limits voltage three to four times that of a regular current. Parallel MOV connections expand life expectancy and increase current capacity. A power strip just adds extra outlet space. A surge protector defends against voltage spikes. Joules are a measurement for energy and will tell you how long your devices will be protected, depending on the strength of the surge.
The devices you plug into your electrical sockets rely on a consistent voltage of electricity. A surge protector defends your electronic devices from voltage inconsistencies by rerouting unsafe energy so that only the normal amount of electricity will pass through your device.
In most residential and commercial spaces in the United States, the standard voltage is volts. On the other hand, it is crucial to use a surge protector with your computer. Laptops and desktop computers are both packed with voltage-sensitive components that a power surge could easily damage. Without a surge protector, a power spike or power surge could shorten the life of your computer, wipe out all of your data, or even completely destroy your system.
In fact, you should use a surge protector with any high-end electronic device. You should always use a surge protector with entertainment centers and gaming consoles, for example.
Your electronics may seem to work fine without a surge protector… at first.
