In a series circuit, how are the components connected?

In a series circuit, the components are connected end-to-end, meaning that the end of one component is directly connected to the beginning of the next component. This creates a single path for the electric current to flow through all the components. Consequently, the same amount of current flows through each component, and the voltage across the circuit is divided among the components based on their resistance.

This configuration is characteristic of series circuits, which contrasts with parallel circuits where components are connected across the same voltage source and allow for multiple paths for current to flow. Connections using a switch can be found in various types of circuits, but they do not define the fundamental structure of a series circuit, and connecting components in parallel paths describes a different arrangement entirely.
