I think it depends on how you heat the water. Electric stoves run on 240 vo= lts, so if you put a tea kettle on the stove it's pretty much the same. Ele= ctric tea kettles that plug into 120 volt outlets are a rarity here. I most= ly use a microwave if I'm making a cup of tea, and it does take a while to = bring the water to a boil.

On the 63rd page, marked page 50, it is said that "In countries where the voltage is 110 volts, it takes twice as long to make a pot of tea." In UK, it is said that a 230V outlet permits up to 13A. So the limit is 2.990kW. In Australia, a 240V outlet permits up to 10A. So the limit is 2.4kW. What does the US have as a conventional pluggable cable limit? Wikipedia suggests 115V and 15A, or 1.725 kW for NEMA 1-15 or 5-15. So that is 58% of the UK tea power delivery. Or 1.73 times as long? -- James Cameron http://quozl.netrek.org/ -- http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
