In this chapter, you will learn about electricity. You will learn about the sources of electrical energy, such as batteries and power plants.
You will also learn about series and parallel circuits, and how to identify and sketch them using symbols. Safety precautions when handling electrical appliances and the conservation of electricity will also be covered.
You will generate ideas on factors that affect the usage of electrical energy and learn about the effects of mishandling electrical appliances.
• Explain with examples the sources of electrical energy
• Identify the arrangement of bulbs in series and parallel in a complete circuit
• Sketch the series and parallel circuit diagrams using symbols
• Compare and contrast the brightness of the bulbs in series and parallel circuits
• Carry out experiments to compare the brightness of bulbs in series or parallel circuit by changing the number of bulbs
• Carry out experiments to compare the brightness of bulbs in series or parallel circuit by changing the number of dry cells
• State the condition of bulbs when a few switches are opened or closed in a series and parallel circuit by carrying out activities
• Explain the observations on series and parallel circuits through written or verbal forms, sketches, ICT in a creative way
• Generate ideas on the factors that affect the usage of electrical energy by carrying out activities
• Explain with examples the effects of mishandling electrical appliances
