Front

During a science project, Grace is using an electronic device that maintains a constant voltage level to her electrical equipment to ensure everything runs smoothly.

Back

AVR

Answer explanation

An AVR (Automatic Voltage Regulator) is designed to maintain a constant voltage level to electrical equipment, ensuring stable operation. Other options like UPS and surge protectors serve different functions.

Front

What PM consists of activities that promote a longer trouble-free life for a device?

Back

passive

Answer explanation

The correct answer is 'passive' because passive maintenance involves activities that enhance the longevity and reliability of a device without requiring active intervention, thus promoting a longer trouble-free life.

Front

During a science project, Anika used an electronic device that maintains a constant voltage level to electrical equipment on the same load to ensure her experiment ran smoothly.

Back

AVR

Answer explanation

An AVR (Automatic Voltage Regulator) is designed to maintain a constant voltage level to electrical equipment, ensuring stable operation under varying load conditions. This makes it the correct choice for the given description.

Front

During a storm, William noticed that the power in his house flickered and then went out completely. He remembered that he had a device that is known as a battery backup, which provides backup power when your regular power source fails, or voltage drops to an unacceptable level.

Back

UPS

Answer explanation

A UPS (Uninterruptible Power Supply) provides backup power during outages or voltage drops, ensuring devices remain operational. Unlike surge protectors or AVRs, it specifically offers battery backup, making it the correct choice.
