a plurality of surface heating elements;

a plurality of sensors configured to monitor an operational status of a corresponding surface heating element;

a first cooking unit;

a second cooking unit; and

an electronic control to facilitate sharing power between said first cooking unit and said second cooking unit based on the operational status of said plurality of surface heating elements.

2. An electric cooking appliance in accordance with claim 1 wherein each of said first cooking unit and said second cooking unit comprises a resistance temperature detector to provide a signal to said electronic control to determine if said corresponding cooking unit requires preheat, said electronic control configured to facilitate sharing power between said first cooking unit and said second cooking unit based on whether said first cooking unit and said second cooking unit require preheat.

3. An electric cooking appliance in accordance with claim 1 wherein each of said first cooking unit and said second cooking unit comprises a bake element, a first broil element and a second broil element.

4. An electric cooking appliance in accordance with claim 3 wherein, during a normal operation of each of said first cooking unit and said second cooking unit, two of said bake element, said first broil element and said second broil element are activated by said electronic control.

5. An electric cooking appliance in accordance with claim 3 wherein said electronic control shares power between said first cooking unit and said second cooking unit by operating at least one of said first cooking unit and said second cooking unit at a reduced power, said operation at a reduced power utilizing one of said bake element and said first broil element.

6. An electric cooking appliance in accordance with claim 3 wherein each of said bake element, said first broil element and said second broil element comprises at least two heating coils, and said electronic control shares power between said first cooking unit and said second cooking unit by controlling a number of said heating coils that are operable within each of said bake element, said first broil element and said second broil element.

7. An electric cooking appliance in accordance with claim 3 wherein:

said first cooking unit bake element is operable at a power of about 2500W, said first cooking unit first broil element is operable at a power of about 2500W, and said first cooking unit second broil element is operable at a power of about 500W; and

said second cooking unit bake element is operable at a power of about 2650W, said second cooking unit first broil element is operable at a power of about 2650W, and said second cooking unit second broil element is operable at a power of about 950W.

8. An electronic system configured for facilitating power sharing, said electronic system comprising:

a plurality of power consuming elements;

a plurality of first sensors each operatively coupled to a corresponding power consuming element of said plurality of power consuming elements, each said first sensor monitoring an operational status of said corresponding power consuming element;

a first unit comprising a first operation element, a second operation element and a third operation element;

a second unit comprising a fourth operation element, a fifth operation element and a sixth operation element; and

a control unit operatively coupled to each of said first unit and said second unit, said control unit sharing power between said first unit and said second unit based on the operational status of said plurality of power consuming elements.

9. An electronic system in accordance with claim 8 further comprising a plurality of resistance temperature detectors operatively coupled to one of said first unit and said second unit, said resistance temperature detectors providing a signal to said control unit to determine a required operation of said corresponding units, said control unit sharing power between said first unit and said second unit based on the required operation of said first unit and said second unit.

10. An electronic system in accordance with claim 8 wherein a normal operation of said first unit utilizes two of said first operation element, said second operation element and said third operation element, and normal operation of said second unit utilizes two of said fourth operation element, said fifth operation element and said sixth operation element

11. An electronic system in accordance with claim 8 wherein said control unit shares power between said first unit and said second unit by operating at least one of said first unit and said second unit at a reduced power, said operation of said first unit at a reduced power utilizes one of said first operation element, said second operation element and said third operation element, and said operation of said second unit at a reduced power utilizes one of said fourth operation element, said fifth operation element and said sixth operation element.

12. An electronic system in accordance with claim 8 wherein each of said first operation element, said second operation element, said third operation element, said fourth operation element, said fifth operation element, and said sixth operation element each comprises at least two electrical coils, said control unit shares power between said first unit and said second unit by controlling a number of said electrical coils that are operable within each of said first operation element, said second operation element, said third operation element, said fourth operation element, said fifth operation element, and said sixth operation element.

13. An electronic system in accordance with claim 8 wherein:

said first operation element is operable at a power of about 2500W, said second operation element is operable at a power of about 2500W, and said third operation element is operable at a power of about 500W; and

said fourth operation element is operable at a power of about 2650W, said fifth operation element is operable at a power of about 2650W, and said sixth operation element is operable at a power of about 950W.

14. A method of operating an electric cooking appliance, said method comprising:

monitoring an operational status of a plurality of surface heating elements using a sensor; and

sharing power between a first cooking unit and a second cooking unit based on the operational status of the plurality of surface heating elements.

15. A method in accordance with claim 14 further comprising:

monitoring whether each of the first cooking unit and the second cooking unit require preheat; and

sharing power between the first cooking unit and the second cooking unit based on whether the first cooking unit and the second cooking unit require preheat.

16. A method in accordance with claim 14 wherein each of the first cooking unit and the second cooking unit comprises a bake element, a first broil element and a second broil element, said method further comprising operating each of the first cooking unit and the second cooking unit by controlling at least one of the bake element, the first broil element, and the second broil element of at least one of the first cooking unit and the second cooking unit.
