Multiple Select

Which of the following statements are true about a series circuit?

• All components are connected end-to-end in a single path.

• If one component stops working, the whole circuit stops working.

• Electricity can take multiple paths to reach the end.

• The circuit remains closed even if one component fails.

Multiple Choice

What is the main difference between a parallel circuit and a series circuit in terms of how components are connected and how electricity flows?

• In a parallel circuit, components are connected at common points, creating multiple paths for electricity to flow. In a series circuit, components are connected one after another, creating a single path for electricity.

• In a parallel circuit, electricity flows in only one path, while in a series circuit, there are multiple paths.

• In a parallel circuit, all components stop working if one fails, while in a series circuit, the others keep working.

• In a series circuit, components are connected at common points, creating multiple paths for electricity to flow.
