Theory
| Number | Name | Description |
|---|---|---|
| 1. | Electricity | This chapter introduces electric current as the flow of electric charges in a circuit. It explains electric potential difference as the work done to move a unit charge. The concept of resistance and the factors affecting it are discussed. Ohm’s law shows the relationship between VI graph |
| 2. | Electricity - Resistivity power energy | This theory explains the concept of resistivity as the property of a material that resists the flow of electric current and depends on the nature of the material. It also explains electric power as the rate at which electrical energy is consumed in an electric circuit and also the joules law. |
