overvoltage
Too much electricity
Overvoltage is electrical voltage exceeding the normal or rated level for a system or component.
Power surges, lightning strikes, and faulty equipment can cause overvoltage, potentially damaging electronics or creating safety hazards.
Surge protectors guard against overvoltage spikes: The overvoltage fried the motherboard.
