A toaster is a small kitchen appliance that uses electric heating elements, typically made of nichrome wire, to brown and crisp bread slices by radiating heat onto them, creating toast when you insert bread into the slots, the electricity flows through the coils, heating them up and causing the bread to toast to your desired level of browning through a combination of infrared radiation, conduction, and convection;most toasters have settings to adjust the toasting time and feature a mechanism to automatically eject the toast when it's done.
