o Electricity (electrical energy)
is one of the many forms of
energy.o Hint: Use the fan example to
analyze the steps of forming
or generating the electrical
energy from the source to the
user
Electrical energy is generated,
distributed and utilized as follows
1
1.The electrical source or generator produces electricity
2
1.The conductor (wires or cables) transfer electrical energy
from the electrical source to the load (users).oApply a practical experiment of
connecting a basic circuit 
oConductors: Iron, Copper, Aluminum
oInsulators: Wood, Rubber & Porcelain
Answer Q4&5 in PF WS 1
Wire of copper as a conductor
o Wires are made of copper, to connect each element
in an electrical circuit with the other
o When using wires (conductors) to connect a voltage
source with a bulb, we enable the current to follow
through the wire to reach the bulb and light it up
Now its connected
through a conductor!!The electrical
circuit we just
connected is a
basic/simple
electrical circuit
that consists of: 
basic/simple electrical circuit:
both drawing are correct, choose the easier for you

The three main elements in an electrical
circuits:
POWER SOURCE CONDUCTORS A LOAD
Answer Q6 in PF WS 1
o What is flowing though the wire ?3
1.The load transforms electrical energy into the kind of energy
required (kinetic in a fan, thermal (heat) in a heater, etc.).Because voltage push the electricity
o What is ohm's law indicating about voltage?
