You're on a roll — here are the solutions to the remaining questions: Question 13: Grade 7 learners were discussing the components of a simple electrical circuit. Which of the following is not a component? A. Fuse B. Dry cells C. Switch D. Connecting wires A simple electrical circuit typically consists of a power source (dry cells), a load (like a bulb, though not listed), connecting wires, and a switch. While a fuse is an important safety device in many circuits, it is often considered an additional component rather than a fundamental one for the simplest circuit diagram, especially in introductory discussions. The diagram provided next to the question also does not show a fuse. The correct option is A. **Question 1
