How do toasters work? Day 4

Toasters aren't the only appliances that turn electrical energy into heat energy. Electric stoves, electric blankets, irons, and even some cars convert electrical energy into heat energy. All of these inventions use filament resistors that can withstand very high temperatures. But sometimes the materials around the filaments cannot. For example, toast left in the toaster too long can turn black or even catch on fire. That's why you should never leave your toaster unattended while you're making toast.
