potential between two points in space. It
makes the charges move.
________2. The unit of resistance.
________3. The measure of the number of
electrical charges passing through a cross
section of a conductor in a given time.
________4. The ability on an object to resist or
hinders the movement of charges.
________5. A power supply.
Column B

Direction: Match column A with column B by writing the correct
letter for the best answer in column A.

6. READ THE FOLLOWING WORDS AND ITS DEFINITION.
(LITERACY)
1. Electricity – is the study of electrical phenomena; it is the branch of science
dealing with such phenomena. Sometimes refer as electric power or electric
energy used in homes.
2. Electric current – is a measure of the number of electrical charges passing
through a cross-section of a conductor in a given terminal.
3. Voltage – is the difference in electrostatic potential between two points in
space, especially between live and neutral conductors or the earth.
4. Resistance – is a force that tends to oppose motion. It resist or hinders the
movement of charges that flows in the current.
5. Load – any component that draws current or power from an electrical circuit.

7. Base on our short activity,
what do you think the title of
our topic for this session?

8. ELECTRICITY:
THE RELATIONSHIP OF
CURRENT, VOLTAGE AND
RESISTANCE

9. LEARNING COMPETENCY:
 INFER THE RELATIONSHIP BETWEEN
CURRENT AND CHARGES
• At the end of the session, the student should be able
to:
• 1. Explain the relationship between current, voltage
and resistance.
OBJECTIVES

- Group 4

18. APPLICATION
1. Why do we need to know about electricity?
Possible Answer: to be aware of electrical energy, because this energy is part of
our lives. Most of the things we do now a days uses electrical energy like:
Cooking, transportation, communication, work and leisure activity.
2. Where do you think this topic can be useful?
Possible Answer: useful in handling electricity safely, Manage and manipulate
electricity.
3. What other ways can we apply this in our daily life?
Possible answer: In saving electricity in the house, Control the use of electrical.
Using light and other devices, prevent accidents cause by electrical faulty.
