Resistors are one of the most fundamental electrical components. They limit the flow of electric current and are measured in ohms. Resistors are critical for controlling voltage and current levels in circuits, ensuring that delicate components do not receive excessive power that could lead to damage. For example, in a simple LED circuit, resistors protect the LED by limiting the amount of current that flows through it, thus extending its lifespan.

The thermostat is equipped with a temperature-sensitive wax or liquid that expands and contracts in response to changes in temperature. When the engine starts and is cold, the thermostat remains closed, preventing coolant from circulating through the radiator. This allows the engine to reach its optimal temperature more quickly. Once the engine warms up to the predetermined temperature, the thermostat opens, letting coolant flow through the radiator to dissipate heat and keep the engine from overheating.
