We all have an intimate relationship with electricity, to the extend that it's really impossible for us to leave without it.

ELECTRICITY AND YOUELECTRICITY AND YOU

2. ELECTRICITY is a
form of energy
resulting from the
existence of charged
particles like
electrons and
protons either as
statically as
accumulation of
charge and
dynamically as a
current.

4. Electrostatics:
the study of
electric charges
at rest, the
forces between
them and the
electric fields
associated with
them.

5. Coulomb: (C) SI unit of electric
charge

6. Atom Structure

7. Atoms are composed of protons (+), electrons (-) and neutrons. The nucleus
contains the protons and neutrons and the electrons surround the nucleus.

8. Atoms are made up of protons, neutrons, and electrons.
Neutrons are neutral and do not have any charge at all.
Protons carry a positive charge, and electrons carry the negative charge.
When an object has a positive charge, it has more protons than
electrons.
When an object has a negative charge, then that object contains more
electrons than protons.

9. Protons are much larger than electrons but have an equal and
opposite charge.

12. Coulombs Law is like the Law of Gravity: Gravitational
forces are always, while electric forces maybe attractive
or repulsive.

15. Electricity and You

16. Internet

17. Humans have an intimate relationship with
electricity, to the point that it's virtually
impossible to separate your life from it. Sure, you
can flee from the world of crisscrossing power
lines and live your life completely off the grid, but
even at the loneliest corners of the world,
electricity exists. If it's not lighting up the storm
clouds overhead or crackling in a static spark at
your fingertips, then it's moving through the
human nervous system, animating the brain's will
in every flourish, breath and unthinking
heartbeat.

electricity to pass through them

21. Electric Field Lines into Negative and out of Positive Charges

23. Electrons are free to move around. When electric charges move, they form
what is called an electric current - the flow of negatively charged particles
through a wire.
