Does E or F on the fuel gauge represent full?
1 Answers
F on the fuel gauge represents full, where F stands for 'full' in English, indicating a full tank; E stands for 'empty', meaning low fuel. When the needle points towards F, it indicates more fuel, while closer to E means less fuel. Many car fuel gauges also have a red section near E, indicating low fuel and the need to refuel promptly. The fuel gauge is used to display the amount of fuel remaining in the car's fuel tank. The fuel level is measured by a float connected to a metal rod inside the tank. The end of the metal rod connected to the float is linked to a variable resistor via a movable contact. The position of the float on the fuel surface in the tank changes the position on the variable resistor through the metal rod. This variable resistor is then connected to the car's fuel gauge, and the movement of the gauge's needle is controlled by the amount of current passing through the variable resistor.
