Here's How Your Car Measures the Fuel in Your Tank 🤯

Описание: Ever wondered how your car knows how much fuel is left? ⛽

Hidden inside the fuel tank is a simple float-and-sensor mechanism called a fuel sending unit.

As the fuel level changes, the float moves up and down. That movement changes the resistance of a variable resistor, sending an electrical signal to the dashboard gauge.

Float up = more fuel.
Float down = less fuel.

A surprisingly simple mechanism hiding inside almost every car. 🚗⚙️
