Which device provides battery-powered backup to protect against power spikes and outages?

• A. Universal Power Stabilizer
• B. Unreliable Power Source
• C. Uninterruptible Power Supply
• D. Utility Power Storage

Answer: (C)

A battery-powered backup device that kicks in instantly when the main power drops keeps equipment running during outages and helps prevent damage from voltage spikes. This is the uninterruptible power supply: it sits between the wall outlet and the equipment, charging its battery when power is available and switching to battery power the moment the main supply fails, providing continuous power and smoothing out fluctuations. The other terms don’t describe a device that both stores energy and delivers immediate backup power, so they don’t fit as well in protecting against outages and spikes.
