Field notes
The calculator models a display as both a series of chained sets and a load distributed across a household circuit, rather than treating “how many sets?” as a single number. Its examples use the relationship between voltage, current, and watts, including separate 80-percent working figures for 120 V and 230 V supplies. Regional sections also distinguish UK fused plugs from Australian and New Zealand unfused plugs.
