CONTENT OF THE LESSON
INTRODUCTION
Electricity is useful because it helps many devices and machines to work. However, for electricity to move from one place to another, it must pass through certain materials. Some materials allow electricity to pass through them easily, while others do not.
Electricity also needs a complete path called an electric circuit before it can power devices such as bulbs, radios, fans, and televisions. Understanding how electricity travels and the materials that help or prevent its movement is important for the safe use of electricity.
In this lesson, pupils will learn the meaning of conductors and non-conductors, the components of an electric circuit, how electricity travels from one point to another, and the various uses of electricity in everyday life.
LESSON 1 – MEANING OF ELECTRICAL CONDUCTORS
Electrical conductors are materials that allow electricity to pass through them easily. These materials help electricity move from one point to another in an electric circuit.
Examples of Electrical Conductors:
- Copper
- Aluminium
- Iron
- Steel
- Silver
- Gold
MEANING OF ELECTRICAL NON-CONDUCTORS (INSULATORS)
Electrical non-conductors are materials that do not allow electricity to pass through them easily. They are used to protect people from electric shock and prevent electricity from escaping.
Examples of Electrical Non-Conductors:
- Plastic
- Rubber
- Wood
- Glass
- Dry cloth
- Paper
Electrical conductors allow electricity to flow through them, while electrical non-conductors do not allow electricity to flow through them. Examples of conductors include copper, aluminium, and iron, while examples of non-conductors include plastic, rubber, and wood.
LESSON 2 – MEANING OF AN ELECTRIC CIRCUITS
An electric circuit is a complete path through which electricity flows from a power source to an electrical device and back to the source. Electricity can only flow when the circuit is complete (closed).
Components of an Electric Circuit
1. Battery (Cell)
- Supplies electrical energy to the circuit.
- It is the source of electricity.
2. Connecting Wires
- Carry electricity from one component to another.
- They provide a path for the flow of electricity.
3. Bulb (Lamp)
- Uses electrical energy to produce light.
- It shows that electricity is flowing in the circuit.
4. Switch
- Controls the flow of electricity.
- It can open or close the circuit.
Simple Electric Circuit Diagram
Battery → Wires → Switch → Bulb → Battery
This forms a complete path through which electricity can travel.
An electric circuit is a complete path through which electricity flows. The main components of an electric circuit are the battery (cell), connecting wires, bulb (lamp), and switch. These components work together to allow electricity to flow and power electrical devices.
LESSON 3 – HOW ELECTRICITY TRAVELS FROM ONE POINT TO ANOTHER
Electricity travels through conductors, such as wires, in a complete electric circuit. For electricity to flow, the circuit must be closed (complete). If the circuit is open or broken, electricity will not flow.
Steps in How Electricity Travels
1. The battery (cell) supplies electrical energy.
2. Electricity flows through the connecting wires.
3. The switch controls the flow of electricity.
- When the switch is ON (closed), electricity flows.
- When the switch is OFF (open), electricity stops flowing.
4. Electricity reaches the bulb or appliance.
5. The bulb lights up or the appliance works.
6. Electricity continues through the circuit and returns to the battery.
Example
In a torchlight:
- The battery supplies electricity.
- The wires carry the electricity.
- The switch allows electricity to flow.
- The bulb lights up when electricity reaches it.
Electricity travels from a power source through wires in a complete circuit. It passes through electrical components such as switches and bulbs before returning to the source. A complete circuit is necessary for electricity to flow and make electrical devices work.
USES OF ELECTRICITY IN EVERYDAY LIFE
Electricity plays an important role in our daily activities. It makes life easier, faster, and more comfortable:
1. It provides light – Electricity is used to light homes, schools, offices, and streets.
2. It powers electrical appliances – It operates fans, televisions, refrigerators, radios, and computers.
3. It supports communication – Electricity helps in charging phones and operating communication devices.
4. It assists learning – It powers computers, projectors, and other learning equipment.
5. It supports healthcare – Hospitals use electricity to power medical equipment and machines.
6. It provides entertainment – Electricity is used for televisions, music systems, and video games.
7. It supports industries – Factories use electricity to operate machines and produce goods.
8. It helps in cooking and heating – Electric cookers, kettles, and ovens depend on electricity.
9. It preserves food – Refrigerators and freezers use electricity to keep food fresh.
10. It makes work easier – Electricity powers machines and tools that reduce human effort.
Electricity is very important in everyday life because it provides light, powers appliances, supports communication, improves learning, assists healthcare, preserves food, and makes work easier. It is one of the most useful forms of energy in modern society.
