You often use a room lit with fluorescent lamps only. Which is the best way to save electricity if you are leaving the room for 10 minutes?
- A.
Switch off the lamp for that 10-minute period
- B.
Leave the lamp on since it does not cost much to have the lamp turned on for 10 minutes.
- C.
Leave the lamp on since the fluorescent lamp uses a large amount of current to re-start
- D.
Either way, there is no difference in the amount of electricity used.
Correct Answer
A. Switch off the lamp for that 10-minute periodExplanation
Switching off the lamp for the 10-minute period is the best way to save electricity because even though fluorescent lamps use a large amount of current to re-start, the amount of electricity consumed during the re-start is still less than the electricity consumed by leaving the lamp on for the entire 10 minutes. Therefore, switching off the lamp is more energy-efficient and helps to save electricity.Rate this question:

- C.
It detects a moving object by emitting ultrasonic waves and receiving these reflected energy, just like a bat.
- D.
It detects the door movement when a person enters or exits a room.
Correct Answer
B. It detects changes in infra-red energy (body heat of the occupant) within the coverage area. It operates by the “line of sight” principle.Explanation
The occupancy (motion) sensor works by detecting changes in infra-red energy, specifically the body heat of the occupant, within the coverage area. It operates based on the "line of sight" principle, meaning it requires a direct line of sight to detect the changes in infra-red energy. This allows the sensor to accurately determine if there is an occupant in the room based on their body heat.Rate this question:
