a slightly elevated voltage lasting from seconds to minutes or more
a slightly decreased voltage lasting from seconds to minutes or more
complete power out lasting a few minutes
alternating power out, power on lasting a few minutes E. has nothing to do with electricity
Answer is Right!
Answer is Wrong!
The correct answer is: B. a slightly decreased voltage lasting from seconds to minutes or more.
A brownout is a decrease in the voltage of an electrical power supply. This can cause lights to dim, appliances to malfunction, and computers to shut down. Brownouts are usually caused by an overload on the power grid, such as when too many people are using electricity at the same time. They can also be caused by problems with the power lines or transformers.
A brownout is different from a blackout, which is a complete loss of power. A brownout is usually less severe than a blackout, but it can still cause problems for people and businesses.
Here is a brief explanation of each option:
- A slightly elevated voltage lasting from seconds to minutes or more is called a power surge. Power surges can damage appliances and electronics.
- Complete power out lasting a few minutes is called a blackout. Blackouts can cause widespread disruption and damage.
- Alternating power out, power on lasting a few minutes is called a rolling blackout. Rolling blackouts are used to manage demand on the power grid during periods of high usage.
- Has nothing to do with electricity is not an option.
