In a series circuit, how are components connected?

In a series circuit, components are connected end-to-end, which means that the current has only one path to follow through each component in sequence. This configuration ensures that the same current flows through all components, and the total voltage across the series circuit is the sum of the individual voltage drops across each component.

When connected in this manner, if any single component fails or is removed, the entire circuit is broken, resulting in all components being turned off. This characteristic of series circuits is crucial for applications where the behavior of each component directly affects the entire operation of the circuit. The end-to-end connection also facilitates the calculation of total resistance and voltage distribution, which can be pivotal in circuit design and analysis.
