Original text

• Electricity (electrical energy)
is one of the many forms of
energy.
• The flow of electricity through
a wire transfers electric energy
from a source to the load
(user).
Example: Fan
• Where is the source of energy?
the socket is the source of energy
• The wire transfers electricity from the source to the user (the
fan).
• The fan is the user or the load, which transforms the electric
energy to mechanical energy as moving fan blades.
Example2: Hair
Dryer
•Where is the source of energy?
the socket is the source of energy
• The wire transfers electricity from the source to the user
(the hair dryer).
• The hair dryer is the user or the load, which transforms
the electric energy to thermal energy.
Based on the example:
analyze how electrical
energy is generated?
• 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).
3
1.The load transforms electrical energy into the kind of energy
required (kinetic in a fan, thermal (heat) in a heater, etc.).
Solve worksheet individually
A. Identify on the figure the source of the energy
The socket
A. Identify the tool that transfers the energy
from source to load
The cable/wire
A. Identify on the figure load (user)
The laptop
A
C
B
Learning Objectives
•Identify the process of generating
electricity.
•Conclude the fundamentals of an
electric circuit.
•Apply a practical experiment of
connecting a basic circuit
•Conductors: Iron, Copper, Aluminum
•Insulators: Wood, Rubber & Porcelain
Answer Q4&5 in PF WS 1
Wire of copper as a conductor
• Wires are made of copper, to connect each element
in an electrical circuit with the other
• 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
Answer Q7 in PF WS 1
+


Power
Source
Load
Conductor
𝑹𝟏
The three main elements in an electrical
circuits:
POWER SOURCE CONDUCTORS A LOAD
Answer Q6 in PF WS 1
• What is flowing though the wire ?
Electricity
• What is the source supplying?
voltage
• Can the electricity flow through the wire without a power supply?
No
• Why?
Because voltage push the electricity
• What is ohm’s law indicating about voltage?
V=IR
• So, what is voltage pushing exactly?
The current
What is the flow of electricity
from source to load is called?
The current
The electric current definition
The electric current is the flow of electricity
Answer Q1 in PF WS 1
BASED ON THIS,
WHAT IS VOLTAGE?
VOLTAGE Definition
VOLTAGE IS THE FORCE THAT PUSHEs THE
CURRENT T
