It is a resistive type of circuit.
A toaster is considered a closed circuit when it is plugged in and turned on, allowing electricity to flow through the heating elements to generate heat. When the toaster is unplugged or the lever is not engaged, the circuit is open, stopping the flow of electricity. Thus, the operational state of the toaster determines whether it functions as a closed or open circuit.

One examples is the batteries in a flashlight, another is a light bulb, a telephone wire tower, power cord, and a toaster. Basically electric energy examples can be things with wire or that work on electricity.
Flashlight: electrical energy -> radiant energyBattery: chemical energy -> electrical energyToaster: electrical energy -> heat energyMotor: electrical energy -> kinetic energy
Ordinary light bulbs, fluorescent tubes, CFLs, flashlight bulbs, LEDs, toaster elements, and laser diodes all do that.
A timing circuit on a toaster regulates the duration of the heating elements' operation, determining how long the bread is toasted. It ensures that the toaster operates for a set period, which can often be adjusted by the user through a dial or lever, allowing for varying degrees of browning. Once the timer runs out, the circuit signals the heating elements to turn off, and often activates a mechanism to pop the toast up. This helps achieve consistent toasting results while preventing overheating.
When using a metal toaster, it is important to follow these safety precautions: Always unplug the toaster when not in use to prevent electrical hazards. Avoid touching the metal surfaces of the toaster while it is in use, as they can become hot and cause burns. Do not insert metal objects into the toaster slots, as this can cause a short circuit or electrical shock. Keep the toaster away from water or other liquids to prevent electrical accidents. Regularly clean the toaster to prevent buildup of crumbs or debris that could pose a fire hazard.
Using a metal knife in a toaster is dangerous because the knife can conduct electricity, increasing the risk of electric shock. It can also damage the toaster, cause a short circuit, or start a fire. It's safer to unplug the toaster and use non-metallic tools if needed.
