How does a toaster timer work?
The simple circuit acts as a timer. A capacitor charges through a resistor, and when it reaches a certain voltage it cuts off the power to the electromagnet. The spring immediately pulls the two slices of bread up. In the process, the plastic bar rises and cuts off power to the toaster.3 мая 2000 г.
What is the purpose of a toaster?

What does the number on a toaster mean?
As the narrator explains, most toasters are too cheap to have a timing chip. Instead, they rely upon a metal strip that curves when heated, and the numerical setting simply tells the toaster how far that strip must bend before it triggers the toast to pop.
Does a toaster use radiation?
A toaster uses infrared radiation to heat a piece of bread (see How Thermoses Work for information on infrared radiation). When you put your bread in and see the coils glow red, the coils are producing infrared radiation. The radiation gently dries and chars the surface of the bread.3 мая 2000 г.
What type of energy does a toaster use?
