Why is the tanker having a small tail behind it? What's the principle?
Your last question, the "tail" of the conductive, not always the electronic conduction to the earth. If the vehicle is positive, it will be sent to the electronic ground vehicle, on the other hand, the electric car to pass on the earth.In short, because of this "tail" of the transmission role, so that the car does not accumulate static electricity
Next interview with you to discuss raw electricity, for reference:A, even if the loading oil did not move, but also because of the flow and external electrostatic dust, air conduction (such as dry day, people live, touch the oil tankers). Then the metal charged "tail" will be the release.B, the oil tanker operation, oil tank and internal friction, will break the original two neutral state, each part of the charge distribution is uneven with static electricity. Then the oil flow has made oil tank and charged, also can make the original charge neutralization, but with the interaction of the outside world, the oil tanker with a whole static, then this "tail" is a discharge.
1, oil tank with static reasons are complex: both oil and tank internal friction, there are also external air and dust, friction with the tank, as well as external electrostatic conduction and many other reasons2, about the cause of the explosion, because you already know, do not say
