Ответить на вопросы Many cars have a fuel warning light. The level of fuel (petrol) in the tank being very low, this light switches on and the driver can see that he needs more petrol. How does this fuel warning light work?
The level of the fuel falling, the float moves downwards. When this happens, the arm also moves downwards and makes the lever touch an electrical contact, thus switching on the fuel light in the car.
Seeing the fuel warning light, the driver puts more petrol into the tank. This makes the fuel level rise and pushes the float upwards. When risen, the float makes the arm move upwards and this causes the level to move upwards also. The fuel warning light then switches off.
1. When does the fuel warning light go on? 2. Why does the float go down? 3. What makes the lever move downwards? 4. Does the float go up or down when the fuel level rises? 5. When does the lever move upwards?
