Question: 1 / 400

How are the loads connected in a series circuit?

In parallel branches

In a loop without intersections

End to end creating a single path for electron flow

In a series circuit, the loads are connected end to end, creating a single path for electric current to flow. This means that the same current travels through each component connected in the circuit sequentially. If one load, such as a light bulb, were to fail or be removed, the entire circuit would become incomplete, and all devices would stop functioning. This configuration is integral to the definition of a series circuit, which emphasizes that all components share the same current flowing through them.

Understanding this structure helps in grasping basic electrical principles, such as voltage division across components and current uniformity throughout the circuit. The characteristics of a series circuit are important for troubleshooting and designing simple electrical systems.
