Final answer:
The correct answer to the question is c) static. An uninterruptible unit is known as a static un-interruptible power supply (UPS)A UPS is a device that provides emergency backup power to a computer or other that uses electronic components to convert and provide backup power during power outages.
Step-by-step explanation:
An uninterruptible unit is known as a static un-interruptible power supply (UPS). A UPS is a device that provides emergency backup power to a computer or other electrical equipment in case of a power outage. Unlike other types of UPS, such as rotary and line-interactive, a static UPS uses electronic components to convert incoming AC power to DC power, which then goes through an inverter to produce the final AC output. For example, if there is a power outage, the static UPS will automatically switch to its batteries to provide power to the connected devices.
This ensures that the devices remain operational without any interruption. Once the main power is restored, the static UPS charges its batteries and switches back to using the AC power. Therefore, the correct answer to the question is c) static as a static UPS refers to an uninterrupted power supply that uses electronic components to convert and provide backup power during power outages.
