2. What is Electricity?
It is a fundamental form of energy
observable in positive and negative forms that
occurs naturally (as in lightning) or is produced
(as in a generator) and that is expressed in
terms of the movement and interaction of
electrons. b : electric current or power.
Electricity, phenomenon
associated with stationary or moving electric
charges. Electric charge is a fundamental
property of matter and is borne by elementary
particles. In electricity the particle involved is
the electron, which carries a charge
designated, by convention, as negative.
Who discovered Electricity?
Electricity was discovered and
understood by many scientists. Benjamin
Franklin is given the credit for discovering
electricity. In the year 1752, Benjamin
Franklin conducted an experiment using a
kite and key on a rainy day. He wanted to
demonstrate the relationship between
lightning and electricity.
Most people give credit
to Benjamin Franklin for discovering
electricity. Benjamin Franklin had one of the
greatest scientific minds of his time. He was
interested in many areas of science, made
many discoveries, and invented many
things, including bifocal glasses.

3. What are the methods of Charging?
There are four methods by which
charges can redistribute themselves to build up
static electricity: by friction, by conduction, by
induction, and by polarization.
There are two types of electric
charge: positive charge and negative charge. If
the same amounts of negative and positive
charge are found in an object, there is no net
charge and the object is electrically neutral.J
In order to charge an object, one
has to alter the charge balance of positive and
negative charges. There are three ways to do
it: friction, conduction and induction.
What is charging by Friction?
Charging by friction: the transfer of
electrons from one uncharged object to. another by
rubbing the two objects together. Some electrons can
move to the. other object when rubbing (hair and
balloon) Charging by conduction: the transfer of
electrons from one object to another by.

What is charging by Conduction?
Charging by conduction is charging by
contact where charge is transferred to the object.
Charging by induction first involves producing a
polarization charge in the object and then connecting a
wire to ground to allow some of the charge to leave the
object, leaving the object charged.

4. What is charging by Induction?
Electrostatic induction, also known as
"electrostatic influence" or simply "influence" in Europe
and Latin America, is a redistribution of electric charge
in an object, caused by the influence of nearby charges.
What is charging by Polarization?
Polarization occurs when an electric field
distorts the negative cloud of electrons around positive
atomic nuclei in a direction opposite the field. This slight
separation of charge makes one side of the atom
somewhat positive and the opposite side somewhat
negative..

According to my understanding, electric
charge is a fundamental property of matter carried by
some elementary particles that governs how the
particles are affected by an electric or magnetic field.
Electric charge, which can be either positive or negative,
exists in discrete natural units and cannot be created or
destroyed.
Additionally, Electric charges are classified
into two types: positive and negative. When two objects
with an excess of one type of charge are relatively close
together, they repel each other. When two objects with
excess opposite charges, one positively charged and the
other negatively charged, are relatively close, they attract
each other. (See also Coulomb force.)
