What occurs to the current in a series circuit?

In a series circuit, the current remains constant throughout the entire circuit. This means that the same amount of electrical charge flows through each component in the circuit without any change in magnitude from one point to another. The total voltage across the circuit is divided among the components based on their resistance, but the current itself does not change.

This characteristic of series circuits is fundamental to understanding how electricity is distributed in such a configuration. Regardless of the number or type of resistive components present, the total current flowing through the circuit is equal at any given point. This constancy is due to the lack of branching paths or junctions that might cause the current to divide, as seen in parallel circuits. This makes the correct answer clear, as it emphasizes that the current does not fluctuate but remains uniform throughout the entire series circuit.
