In a series circuit, all components are connected end-to-end in a single path for current to flow. This means that the same current flows through each component in the circuit. This is a fundamental property of series circuits: because there is only one pathway for the current, the amount of charge flowing per unit time is the same at every point in the circuit.

When a series circuit includes resistors or other components, the total resistance is simply the sum of the individual resistances, which affects the overall current based on Ohm's Law (I = V/R, where V is the total voltage and R is the total resistance). Since there is only one path for the current, irrespective of the resistance values of the individual components, the overall current remains constant throughout the circuit.

In contrast, a parallel circuit has multiple paths for current to flow, which can lead to different currents in different branches, depending on the resistance in those branches. A combination circuit may contain both series and parallel components, which further complicates the current flow, making it varied across the circuit. An open circuit, on the other hand, is not complete, meaning that current cannot flow at all. Thus, the defining characteristic of a series circuit is that it ensures the same
