What happens to current in a series circuit?

In a series circuit, the defining characteristic is that the same current flows through all components connected in that circuit. This means that regardless of the number of resistors or other devices present, the current remains constant across the entire series. The electrons move through each component sequentially, and since there is only one path for the current to take, all of it flows uniformly through each part without division or variation.

This concept is foundational in understanding how series circuits operate. While components in a series can have different voltage drops across them due to their resistance values, the total current flowing through the circuit stays the same. Thus, the stability of the current in a series circuit is an essential point to grasp when studying electrical principles related to circuits.
