Which characteristic is true for a series circuit?

In a series circuit, all components are connected end-to-end, forming a single path for current to flow. This means that the same amount of current passes through each component in the circuit. When one component is connected after another in a series arrangement, they all share the same current, which is a fundamental characteristic of series circuits. This uniform current flow means that if one component fails or is removed, the entire circuit is interrupted, and no current can flow.

The other options do not accurately describe the nature of series circuits. In a series circuit, current cannot flow through multiple paths; that characteristic applies to parallel circuits. Additionally, unlike what is suggested, adding more components in a series circuit actually increases the total resistance, making it more challenging for current to flow instead of decreasing it. Finally, while the ease of repair can depend on the specific context or design, series circuits are generally not considered the easiest to repair, especially because a failure in one component affects the entire circuit’s functionality.
