The effects of static electricity are explained by a physical quantity not previously introduced, called electric charge. There are only two types of charge, one called positive and the other called negative. Like charges repel, whereas unlike charges attract. The force between charges decreases with distance.
When a capacitor is charged, a static electric field exists between the plates. This results from the electrons being pumped from the positive to the negative plate and the attraction between them and their counterpart positive ions. The actual value of stored energy depends on the capacity and voltage of the capacitor.
Some of the most basic characteristics of static electricity include: The effects of static electricity are explained by a physical quantity not previously introduced, called electric charge. There are only two types of charge, one called positive and the other called negative. Like charges repel, whereas unlike charges attract.
As the electric field is established by the applied voltage, extra free electrons are forced to collect on the negative conductor, while free electrons are “robbed” from the positive conductor. This differential charge equates to a storage of energy in the capacitor, representing the potential charge of the electrons between the two plates.
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.
When the voltage across a capacitor is increased, it draws current from the rest of the circuit, acting as a power load. In this condition, the capacitor is said to be charging, because there is an increasing amount of energy being stored in its electric field. Note the direction of electron current with regard to the voltage polarity:

Nearly everyone is familiar with the static charge generated by friction — a phenomenon formally known as triboelectricity. Walking across a carpeted floor, combing one''s hair on a dry day, or pulling transparent tape off a roll all result in the separation of small amounts of positive and negative charge.
Static cling generated in a clothes dryer and the attraction of straw to recently polished amber also result from rubbing. Similarly, lightning results from air movements under certain weather conditions. You can also rub a balloon on …

Static electricity gets build up by two processes-friction and induction.This static electricity gets stored in both the objects involved in the process of induction and friction. But after sometime there is a imbalance of charges on the objects (positively and negatively charged).So in order to balance the number of electrons and protons in ...
Static electricity can be created by rubbing one object against another object. This is because the rubbing releases negative charges, called electrons, which can build up to produce a static charge. For example, when you shuffle your feet across a carpet, electrons can transfer to you, building up a static charge on your skin. You can suddenly discharge the static charge as a …
This moisture can reduce static build-up. However, in drier US states, static shocks might be more frequent. Clothing: Synthetic fibers, popular in both regions, can increase static electricity. However, the type of shoes, prevalent in each region, can also play a role. Rubber-soled shoes, popular in the US, can increase static, especially on ...
If you had a much stronger source, like a van de graff generator, and placed it close to the cap you could probably charge it and create a ''semi'' hazardous voltage on the capacitor (but it probably wouldn''t be any different than touching the van de graff generator) It is a concern that capacitors can develop a dangerous charge and be discharged ...

To prevent static electricity from damaging chips, it is important to take precautions such as wearing an anti-static wrist strap, using an anti-static mat, and handling chips and other electronic devices with care. It is also important to avoid working in dry environments or wearing clothing made of materials that are prone to static buildup.
Chapter 1 of this book began with an explanation of static electricity, and how materials such as wax and wool—when rubbed against each other—produced a physical attraction. Again, physicists would describe this interaction in terms of electric fields generated by the two objects as a result of their electron imbalances. Suffice it to say ...
