James, Kai, and David are having a debate. They are trying to identify a device that transforms electric energy into thermal energy. James thinks it's a convection current, Kai believes it's a heating appliance, and David is convinced it's thermal contraction or thermal expansion. Who do you think is correct?
James - convection current
Kai - heating appliance
David - thermal contraction
David - thermal expansion
