Voltage spikes refer to sudden and brief increases in voltage that occur in electrical circuits. These spikes can cause significant damage to electronic devices and appliances. To avoid such problems, it is important to have an understanding of the synonyms for the term voltage spike. Some of these are transient surge, voltage surge, electrical surge, electrical spike, power surge, and power transients. Whatever the term used, the effect is the same: any current, voltage, or power increase above the usual level can lead to equipment failure, data loss, or even fires. Therefore, it is important to protect sensitive electronics from voltage spikes by using devices such as surge protectors and voltage regulators.
