Some doubt remains about whether Franklin
actually performed the kite experiment,
because he failed to mention it for some time.
The European demonstrations, however,
made Franklin famous. Franklin also published
instructions on how to protect houses with
lightning rods.
7. ELECTROSTATICS…
Lightning is considered as a static electricity.
Electricity began with man’s curiosity on the
peculiar ability of amber and loadstone to attract
other materials. Loadstone is known today as
magnetized iron core. Amber is a translucent
yellowish-brown fossil resin.
Thales of Miletus – 1st
recorded investigator of
ability of amber.
Electrics – comes from the Greek word elektron
meaning “amber”.
8. ELECTROSTATICS…
Electrostatics is the study of all phenomena
associated with charged bodies at rest.
Static electricity has always been a part
of our daily experience, although we
are not aware of it. We feel a very mild
electric shock when we walk across a
carpet and reach out for the knob or
any metallic object. We see the so-
called “fly away hair effect” when we
comb our hair several times. This comb
may even attract small pieces of paper.

The modern theory of electric charges
is the electron theory. It explains the
existence of charges by the structure of
an atom. An atom is made up of
positively charged nucleus surrounded
by negatively charged electrons. The
nucleus contains the positively charged
protons and uncharged neutrons.
Bodies that provide electricity are known
to be charged. Charges are classified
into positive and negative charges.
