11.1 Series circuits | Series and parallel circuits | Siyavula

A series circuit is the simplest way to connect components. In this setup, all parts are connected end-to-end, forming a single loop for the electrons to flow through. There is only one way for the current to go.

Household wiring. This is why you can turn off your bedroom light without the refrigerator turning off. Key Comparisons for Grade 8 Series Circuit Parallel Circuit Current Same everywhere Splits between branches Voltage Shared across components Same for each branch Failures One break stops everything One break only stops that path Bulb Brightness Decreases as more are added Remains the same Conclusion

Adding more resistors in parallel causes total resistance to... a) Increase. b) Decrease. c) Stay the same.
