Unit 4 (Electricity): Solutions to the Workbook Activities

Hi everybody ! As you know you will be taking the exam for unit 4 next week. Apart from reviewing  the IT Activities you have been working on over the last 6 weeks in the computer room, you may also complete the activities in your workbook with the help of the animation below. In the exam you will have to identify the components of an electric circuit (power supply, control devices, load devices and conductor), explain how the circuit works, calculate voltage drops in a circuit, etc. You will find activities with these questions in your work book. Good luck.
