Electrostatics is the stationary or slow moving electric charges with no acceleration.
When the electric charges accelerate on the surface of the object, it makes the electrostatics. The electric charges can be divided into positive charge and negative charge.
The positive charges makes the positive electrostatics and the negative charges makes the negative electrostatics. Nomatter the positive electrostatics or the negative electrostatics, when the object with the electrostatics contact the zero potential object, the charge transfer will happens.
A. Electric charge quantity
It shows the electrostatics electric charge quantity. It often use Q to stand. And C for the unit.
B. Electrostatics pressure
Because the electrostatics pressure is very higher. We generally use KV for the unit.
