Electrostatics

voltaicity
Electricity is the flow of electrical power or focussing.
Electric Charge
Common symbolQ, q (special symbol for the charge on 1 electron or proton is e)
SI unitcoulomb, C
Electric charge is a property possessed by atoms. All matters ar made of atoms. An atom is basically composed of three unalike components -- electrons, protons, and neutrons

Protons and electrons possess electrical charge which creates an electrical field, which is a voice of space in which rip are exerted on former(a) bodies with charge.
Note:
There are two kinds of electrical charges, domineering and detrimental.
Like charge (+ and +, or - and -) repel; unlike charges (+ and -) decoy within the electric field

The charges carried by protons and electrons within atoms are compare in magnitude by opposite in signs. Protons track down positive charges, while electrons carry contradict charges.
Neutrons are electrically neutral
An atom is electrically neutral, which means that there are pair numbers of protons and electrons. Positive charge of protons is balanced by negative charge of electrons. It has no net electrical charge.
Charge particles roll in the hay an electrical force within the electrical field
The force among electrons is weak, hence electrons can move easily
When atoms gain or pull away electrons, they are called ions.
? A positive ion is a cation that misses electron(s).
? A negative ion is an anion that gains extra electron(s).

Electric Field

Electric field lines can be drawn using field lines.

They are also called force lines.
The field lines are originated from the positive charge and end up at the negative charge.
