I think I am right in the thought that if a kettle draws 10amps at
240volts
to create 2400W of power, then reducing the volts to half (110v approx.)
will require approx. 20amps to create the same power. (unless I have
forgotten something else - like the variation in resistance of the
element
as you increase the current ... ?). So either murkin mains electricity
must
be capable of supplying far greater current (double) for the same power
rating, or their kettles take twice as long to boil ... !
household circuits are 15A, unless they are dedicated ones for electric
range/oven or dryer or water heater or aircon, which are 240v i think (not
sure, all gas at home)
