Which characteristic is true for series circuits?

In a series circuit, one of the defining characteristics is that the current remains the same through all components. This is due to the way series circuits are constructed: there is a single pathway for the current to flow. When current passes through each component in the series, it does so in the same quantity, meaning the same amount of charge flows through each component per unit time.

As a result of this uniform current flow, if you were to measure the current at any point in the circuit, you would find it to be the same regardless of where you measure. This characteristic is fundamental to understanding how series circuits function and is essential for calculating other electrical properties, such as total resistance and voltage drops across individual components.

It's this consistency in current that differentiates series circuits from parallel circuits, where current can vary through different branches.
