A classic toaster (bread toaster) is mostly radiation with a little convection. The heating elements radiate their heat onto the contents of the toaster. (In a "toaster over" there is much more convection when the oven is closed, and it functions like a conventional oven, cooking mainly with the trapped heated air.)
actually, there is usually a sticker under your toaster. The amount of watts, and volts can change from different companies, and the size of toaster you have. My toaster can fit 4 pieces of toast and it uses 120 volts and 1500 watts
Your setting a temp very much like a toaster oven.
