B. CONCEPT/IDEAS: Electric Circuit, path of an electric current. The term is usually taken
to mean a continuous path composed of conductors and conducting devices.
C. REFERENCES: Electrical installation and maintenance k12 learning module
Industrial Arts for Secondary Education ( Exploratory)
Basic Electricity Second Edition (Handbook)
Encarta Encyclopedia (2007 Edition)
Encarta Dictionary (2007 Edition)
D. MATERIALS: Cartolina, Pentelpen, Chalk, PDX wire, switch, junction box, electrical tape,
side cutter, long nose pliers, combination pliers, lamp holder, illustration boad.
VALUE FOCUS: Awareness of students about Electric Circuit.
III.
PROCEDURE:
A. PRE-ACTIVITY
I. PRAYER
II. REVIEW
QUESTIONS:
 What are the sources of electricity?
 A source of electricity which is formed from natural matter such oil, and
natural gas?
 A source of electricity that comes from the force of a moving air?
TEACHER’S ACTIVITY
“Now, we know already where did the electricity came from. But the
question is, how it is distributed to every consumer?
B. ACTIVITY PROPER
I. PRESENTATION OF LESSON:
TEACHER’S ACTIVITY
“TODAY, we’re going to talk about electric circuit. What is electric circuit?
II. UNLOCKING OF DIFFICULTIES:
TEACHER’S ACTIVITY
“The Encarta Dictionary defines Circuit as a Circular path or a route.”
III. DISCUSSION
 ELECTRIC CIRCUIT
O A complete path where electricity flows from the source to the load.
 THE FOUR ESSENTIAL PARTS OF ELECTRIC CIRCUIT
A. Source – provide the electrical pressure in the circuit.
Example:
Battery & AC outlet
B. Conducting path – brings the electricity towards load.
Example:
Metal conductor
C. Controlling device/ switch – controls the flow of electricity,
depending upon the discretion of the operator.
D. Load – converts electricity to other form of energy.
Example:
Electric motor, light bulb. Television, refrigerator, etc.
I.
TYPES OF ELECTRIC CIRCUIT
There are two types of electric circuit , called series and parallel.
The components in a circuit are joined by wires.


if there are no branches then it's a series circuit
if there are branches it's a parallel circuit
A.
Series circuits
In a television series, you get several episodes, one after the other. A series circuit is similar. You get
several components one after the other.
If you follow the circuit diagram from one side of the cell to the other, you should pass through all the
different components, one after the other, without any branches.
If you put more lamps into a series circuit, the lamps will be dimmer than before.
In a series circuit, if a lamp breaks or a component is disconnected, the circuit is broken and all the
components stop working.
Series circuits are useful if you want a warning that one of the components in the circuit has failed. They
also use less wiring than parallel circuits.
B.
Parallel circuits
In parallel circuits different components are connected on different branches of the wire. If you follow
the circuit diagram from one side of the cell to the other, you can only pass through all the different
components if you follow all the branches.
In a parallel circuit, if a lamp breaks or a component is disconnected from one parallel wire, the
components on different branches keep working. And, unlike a series circuit, the lamps stay bright if you
add more lamps in parallel.
Parallel circuits are useful if you want everything to work, even if one component has failed. This is why
our homes are wired up with parallel circuits.
IV.
APPLICATION
TEACHER’S ACTIVITY
Provided with materials. Let the students assemble the four (4) essential parts of
electric circuit. Instructions and safety rules must be discussed before the activity starts. The
performance will be judge using the following criteria.

your answer on the space provided.
1. It controls the flow of electrons.
2. It provides pressure in the circuit.
3. It allows individual to regulate electricity.
4. It converts electricity into other forms of energy.
5. It is a complete path where electricity flows.
 ENUMERATION:
O Direction: Enumerate the following items being asked.
1-4 Essential parts of electrical circuit.
5- 8 Examples of load in electric circuit.
8-10 Types of electric circuit
VI.
ASSIGNMENT
- In a ¼ sheet of pad paper, explain what will happen to the electric circuit if the
electricity will return to the source without passing the load. 10 pts.
