1. An electric heating element, comprising:
an electrically resistive inner heating element including an inner coiled heating portion and first and second cold legs extending from and underneath the inner coiled heating portion for connection to an electrical power source;
an electrically resistive outer heating element including an outer coiled heating portion positioned in a common plane with and around the inner coiled heating portion, the inner and outer coiled heating portions defining a working surface for receiving a cooking utensil thereon, the outer heating element including third and fourth cold legs extending from and underneath the outer coiled heating portion for connection to the electrical power source, wherein
the third cold leg is positioned adjacent to and directly above the first cold leg and the second cold leg is positioned between the third and fourth cold legs, and
the inner heating element is electrically wired in parallel with the outer heating element, wherein first and second conductors extending from the respective first and second cold legs are electrically joined with respective third and fourth electrical conductors extending from the respective third and fourth electrical conductors, wherein the third and fourth electrical conductors are configured for engaging with an appliance electrical receptacle having a single pair of electrical conductor receiving ports;
a medallion positioned below the working surface and inside the inner coiled heating portion; and
a switch positioned in electrical series along the second cold leg and in proximity to the medallion, the switch configured to selectively open and close an electrical circuit to turn off and on the inner coiled heating portion.
