Laptop in use vs Electric kettle
What are they, and what does the difference actually look like?
Two things. One honest scale.
Meet the pair
What these two things are
Electric kettle

Power is energy per unit time: one watt is one joule per second.
Measurements, assumptions & sources +
Laptop in use
A chosen 50 W electrical draw. Workload affects actual consumption.
Defined examples — our methodology
The marked power is calibrated. Unmeasured illustration details are representative.
Electric kettle
A chosen 3,000 W input. Power is the rate of energy transfer.

- Electric kettle is larger on this measurement by a factor of about 60.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Laptop in use is labelled example; treat the displayed value as a comparison anchor rather than false precision.
- Electric kettle is labelled example; treat the displayed value as a comparison anchor rather than false precision.
