Electricity is the movement of electrons
between the atoms that are either positively
or negatively charged.
An atom that loses electrons has positive charge
An atom that gains electrons have negative
charge
Also defined as a variety of phenomena
resulting from the presence and flow of
electric charge
Thales of Miletus (630-550 BC)
The first to acknowledge that the amber stone when
rubbed produces an attraction force over some object
William Gilbert (17th century)
Studied phenomena of electricity and magnetism,
and distinguished between the electric effect of
amber and magnetic effect of lodestone
Gave name ‘electricus’ to the phenomena of
attraction shown by amber
▪ Rise to the modern word of electricity
Benjamin Franklin (18th century)
Known as the father of electricity
Kite experiment
Performed experiment of flying a kite during a
thunderstorm
Discovered that lightning and electricity were
somehow related
Alessandro Volta
Constructed the first device to produce a steady
electricity, voltaic pile (electric battery).
▪ Positive and negative charged connectors created
transmission of electricity.
Michael Faraday
Created the electric dynamo, a precursor of
modern power generators
Opened the door to the new era of electricity
Nikola Tesla
Developed the first actual power system
Developed florescent lights and publically used it
prior to Ericson’s invention of the incandescent
light
Static Electricity
A condition that exists when electrons are
displaced and remain
Usually result of friction, such as lightning bulb
Current Electricity
A constant flow of electrons from atom to atom
Historic View
Perceived electricity as the power of the Gods
Ex: Certain species of eels and rays, possess the
defensive power to generate electric shocks and
ancient people thought these shocks could cure
headache or gout.
▪ They did not, however, use the term ‘electricity’ for what
they were experiencing.
Housing System
Enlighten rooms with kerosene lamps instead of
stands or incandescent lights, and heated up the
rooms with wood or coal stoves instead of electric
heater.
Transportation
Transportations such as car and train could not be
produced due to lack of electricity.
People had to travel by walk or carriage.
Telecommunication
Used smoke or fire to deliver urgent news or
location
Economy
Raised horses and cows for economic activity
Increased traveling time by riding carriage or
horse
Poor quality of life with lack of technology and
electricity
Thermoelectric Power Generator
Hydroelectric Power Generation
Nuclear Power Plants
1. Power plant gather to
heat up water
2. Vapors water
3. The water goes into a
big tube that travels
to turbine
4. Spins a magnet inside
the generator to
make electric force
1. Generated by the force of
falling water
2. Water flows through a dam
and turns a turbine, which
turns a generator
▪
Turbines contain metal coils
surrounded by magnets that
spin over the metal coils, which
produces electricity
Steam power plant that is fueled by a
radioactive element such as uranium.
The fuel is placed in a reactor and the individual
atoms are allowed to split apart.
2. The splitting process releases great amounts of
energy that is used to heat water until it turns to
steam.
3. The mechanics of a steam power plant take over
that it pushes on turbines, which force coils of wire
to interact with a magnetic field to produce an
electricity

Entertainment
Enable us to watch television, listen radio and
music, and use electric devices such as cell phone
and personal computer
Comfort
Help housework with washing machine, vacuum
cleaner, microwave, etc.
Enable us to read or work at night as bright as
noon time
Information System
Usage of cell phone or internet with electricity
base enable us to get new information faster than
any other time
Ex: Stock market, international telephone service
Medical Service
Enable us to use x-ray, CT scan, MRI, CPR device
etc.
Provide better surgery with modern technology
Sewage Treatment
Remove contaminants from wastewaters and
household sewage with chemical, biological and
physical methods based on electricity usage
Industrialization
Promoted heavy industries and massive
production
Decreased time cost and labor forces with
developed technology and electricity
Sound
The electrical interaction will create a force that
move electrons in and out together, which creates
a sound wave
Speed of moving in and out is the frequency of the
sound, or pitch, and the amount of the cone
movement is the amplitude of the sound, or
volume
Ex: Speaker
Light
Electrical energy into the metal flows into the
circuit such as light bulb
In circuit, amount energy was delivered these
electrons pass along the filament
Heat
The resistance of electrons flowing through
conductors produce heat energy
Ex: Electric stove, electric pad, iron
