What type of circuit configuration results in all components sharing the same current?

1. Series circuit

2. Parallel circuit

3. Complex circuit

4. Open circuit

The correct answer is: Series circuit

In a series circuit configuration, all components are connected end-to-end in a single path for the current to flow. This means that there is only one pathway for the electrical current to travel through, which results in the same amount of current passing through each component. Because the current remains constant throughout the entire circuit, each component experiences the same flow of electrical charge. In contrast, a parallel circuit has multiple pathways for current to flow, allowing different components to have different currents running through them. A complex circuit typically includes both series and parallel arrangements, leading to varying currents in different branches. An open circuit, by definition, does not allow current to flow at all due to a break in the path. Thus, the nature of a series circuit ensures that all components share the same current, making it the correct choice for this question.
