11. Electricity
Electricity is a form of energy that powers many devices used in our daily life. In this lesson, students learn about electric current, which is the flow of electric charges through a conductor such as a metal wire. The chapter explains important concepts like electric potential difference, resistance, and Ohm’s law, which describe the relationship between current, voltage, and resistance in an electric circuit.
Students also study how electrical components are connected in series and parallel circuits and how these arrangements affect the flow of current. The lesson further introduces the concept of electric power and electrical energy, helping students understand how electricity is used in household appliances, lighting systems, and electronic devices. This chapter builds a strong foundation for understanding how electrical systems work in everyday life.
