  • the electric terminals 22 are arranged so that when the cooking vessel 2 is placed on the cooker 4, at least one pair of electric terminals 2 make electrical contact with the cooking vessel 2 and are electrically shorted by the heating resistor of the cooking vessel. Thus, when a voltage is applied between the electric terminals 22 of the at least one pair of electric terminals 2, a current flows between the electric terminals 2 through the heating resistor and the heating resistor heats the cooking vessel 2.
  • the memory 24 stores a computer program 32 which when executed by the processor 28 allows the processor to perform the method of any of Figures 6 to 8 (discussed in further details below).
