A POWERPOINT ABOUT CIRCUITS

1. Introduction to Circuits An electric circuit is a closed loop or pathway that allows electricity to flow. It's like a path that electricity flows along. Circuits are used to power all sorts of electrical devices. by Jamille Ian Ampe

2. What is an Open Circuit? 1 No Path for Electricity An open circuit is a broken or incomplete pathway that prevents electricity from flowing. 2 Non-Functioning Devices in an open circuit won't work because there's no complete pathway for the electricity to travel. 3 Example Think of a flashlight with a missing battery, making the circuit open and the flashlight unlit.

3. Characteristics of an Open Circuit Broken Pathway Visual representation of a broken wire, illustrating the open pathway that prevents the flow of electricity. Non-Functioning Device An unlit bulb due to an open circuit, showcasing the inability of electricity to complete the pathway and illuminate the bulb. Incomplete Circuit An illustration of an incomplete circuit, depicting the non-continuity of the pathway.

4. Examples of Open Circuits Bulb without Battery An open circuit example where a bulb fails to light up due to the absence of a battery, causing the pathway to be incomplete. Switched Off Lights When a light switch is turned off, the circuit is open, and the light doesn't illuminate. Disconnection If a wire is disconnected, it creates an open circuit, disrupting the flow of electricity.

5. What is a Closed Circuit? 1 Complete Pathway A closed circuit is a complete pathway, allowing electricity to flow without any interruptions. 2 Functioning Devices In a closed circuit, devices work as the pathway is complete, allowing electricity to power the devices. 3 Example A flashlight with a properly inserted battery is a closed circuit, leading to the illumination of the bulb.

6. Characteristics of a Closed Circuit Continuous Flow In a closed circuit, electricity flows continuously through the complete pathway. Functionality Devices operate as usual in a closed circuit, as electricity powers the devices efficiently. Circular Path The electricity follows a circular path, traveling from the source to the device and back to the source.

7. Examples of Closed Circuits 1 Light Switched On When a light switch is turned on, the circuit is closed, allowing electricity to illuminate the light. 2 Closed Doorbell Circuit Pressing a doorbell button closes the circuit, activating the chime. 3 Battery-Powered Toy Operating a toy with a closed circuit, where the battery powers the toy's functions.

8. Conclusion Key Takeaway Understanding open and closed circuits helps in troubleshooting electrical issues and ensuring proper functionality of devices. Application Knowing how circuits function is crucial for safely working with and repairing electrical devices and systems.
