voltage surge
Electrical current spike
A voltage surge is a sudden, brief increase in electrical voltage above normal levels.
Surges can damage sensitive electronics and appliances by overwhelming their circuits.
Lightning strikes, power grid fluctuations, and heavy equipment cycling on and off are common causes.
Surge protectors guard against these spikes: The voltage surge fried my computer's motherboard.
