Static Electricity can be dangerous Fuel Tank • As fuel flows out of a filler pipe it gets positively charged, because the pipe scratches electrons off the fuel • The positive charges distribute on the surface of the tank • If enough potential is built up a spark can occur • And…
Static Electricity can be dangerous Metal pipe Connection to the earth • Explain how making the filler pipe of metal and connecting the tank to the “earth” solves the problem • Connecting the tank and the pipe to the earth allows the charges to move away • The nozzle made of metal conducts the charges away rather than building up
Write bullet points to describe how lightning form • Water from the cloud scratches away electrons from the rain droplets • The droplets carry positive charges and deposit them on the ground • A very high voltage builds up between cloud and ground • A massive spark is the means through which the negative charges travel to the ground to discharge the cloud
