In which type of circuit is DC current the same through all components?

A series circuit is defined as a circuit where all components are connected end-to-end, forming a single continuous path for the electricity to follow. Because there are no alternate routes or branches, the exact same electrons must flow through every single component. Therefore, the direct current (DC) remains identical through all parts of a series circuit. If you measure a current of 2 amperes at one point in a simple series circuit, it will be 2 amperes everywhere else. In contrast, a parallel circuit has multiple paths, meaning the total current splits and can be different in various branches depending on their resistance. However, in a parallel circuit, it is the voltage across each component that remains the same, not the current.
