An electrical circuit is a passage connected by battery, leading wire, switch and more. A flashlight can be made by linking these electrical components and connecting circuits. Learn about closed circuits that allows current to flow, thus lighting the bulb in the circuit. On the other hand, discover how breaks in the electrical passage can disrupt current flow, which results in the bulb not being able to light up.
Science Learning Objectives:
- Recognise that an electric circuit consisting of an energy source (battery) and other circuit components (wire, bulb, switch) forms an electrical system.
- Show an understanding that a current can only flow in a closed circuit.
