This document provides an introduction to basic electricity concepts. It defines electricity as the flow of charge and discusses electron theory. It also covers the differences between conventional current flow and true electron flow. Additionally, it defines conductors, insulators, and semiconductors based on their electrical conductivity. The document introduces alternating current and discusses AC generators, induction motors, and transformers which are used to increase or decrease voltages in power applications.

What is Electricity?
Electricity is the flow of charge.

POWER PLANT FUNDAMENTAL
Electron Theory
Atoms comprised of
protons, neutrons and
electrons.
A molecule is the smallest
part of matter which can
exist by itself and
contains one or more
atoms.

The ability of the material to either
allow or impede the flow of
electrons.

CONDUCTOR
An material that allows
the flow of an electrical
current in one or more
directions

8. BASIC ELECTRICITYPOWER PLANT FUNDAMENTAL
An electrical insulator is a material
whose internal electric charges do
not flow freely, and therefore make
it nearly impossible to conduct an
electric current
INSULATOR

Semiconductor
Materials that have the resistance
levels between those of a
conductor and an insulator are
referred to as semiconductors.

Transistors
A transistor is a semiconductor
device used to amplify or switch
electronic signals and electrical
power. It is composed of
semiconductor material usually
with at least three terminals for
connection to an external
circuit.

PROPERTIES OF MAGNET
1. Magnets attract objects of iron, cobalt and
nickel.
2. The force of attraction of a magnet is greater
at its poles than in the middle.
3. Like poles of two magnets repel each other.
4. Opposite poles of two magnets attracts each
other.

Electromagnetism
The interaction of electric currents or fields and magnetic fields.

Transformer
A transformer is to transfers electrical
energy between circuits through
electromagnetic induction
Transformers are used to increase or
decrease the alternating voltages in
electric power applications.
