What is Static Electricity (Electrostatics)

Static Electricity:-

Now, we will discuss the behaviour of static electricity and the laws governing it.In  fact, electrostatics is that branch of science which deals with the phenomena associated with electricity at rest.

Generally an atom is electrically neutral  i.e in a normal atom the aggregate of the  positive charge of protons is exactly equal to the -ve charges of electrons.

Attraction & repulsion

If,somehow, some electrons are removed from the atoms of a body, then it is left with a preponderance of positive charge. It is then said to be positively-charged. If. on the other hand,some electrons are added to it, negative charge out-balances the positive charge and the body is said to be negatively charged.

In brief, we can say that positive electrification of a body results from a deficiency of the electrons whereas negative electrification results from an excess of electrons.

 The total deficiency or excess of electrons in a body is known as its charge.
