How is electrical current described in a series circuit?

In a series circuit, electrical current is described as having a single path. This means that all components in the circuit, which may include resistors, lights, or other devices, are connected one after another in a sequential manner. Consequently, the same amount of current flows through each component with no branching paths available for the current to follow.

If any component in the series circuit is disconnected or fails, the entire circuit is broken, and current ceases to flow. This characteristic of a series circuit ensures that the current remains constant throughout, as there are no alternative routes for the current to take. This one-path setup is fundamental to understanding how series circuits function in various electrical applications.
