| + | [* black] How it works: When the lever is pressed, the two copper strips are pushed forward and come into contact with an electromagnet that begins the simple toaster circuit. |
|---|---|
| + | [* black] The current flows through a large resistor that wraps around the toaster and slowly gets hot which is what allows the toast to cook. |
| + | [* black] A capacitor connected to the circuit charges through the resistor, and when it reaches a certain voltage it cuts off the power to the electromagnet. |
| + | [* black] The spring immediately pulls the slices of bread up. |
| + | [* black] In the process, the lever rises and cuts off power to the toaster. |
| + | [* black] The darkness setting (below the lever) uses a bi-metallic strip which heats up when the circuit is on and depending on what setting you have it on, the strip bends for a certain amount of time and eventually trips a switch that kills the power to the electromagnet. |
