What type of circuit has all its components connected end to end?

A circuit where all components are connected end to end is defined as a series circuit. In a series circuit, the entire current passes through each component sequentially. This configuration means that the total resistance is the sum of the individual resistances, leading to a consistent current throughout the entire circuit. If one component fails or is removed, the circuit becomes open, interrupting the flow of current for the whole circuit.

The properties of a series circuit also include that the voltage across each component can be different, depending on its resistance, but the total voltage of the power source is shared among all components. This principle is essential for understanding circuit behavior and troubleshooting in electrical systems.
