What type of heat transfer is found in an electric oven?

CONVECTION.


Electric current is passed through a high resistant coil causing the coil to heat up, the hot coil heats up the air in the oven %26amp; in turn through convectional currents, the hot air heats up the food or whatever in the oven.


Pretty simple isnt it??|||Mostly Convection, by transferring heat energy through the air, and to a certain extent, Radiation, by radiant heat, which means that infra-red energy (light) is being emitted by the hot metal.





There won't be much heat transferred by conduction unless the heating element is toughing the food... which is quite unlikely.





The three ways to move heat around are convection, conduction, and radiation.
