In a series circuit, what is true about the current?

In a series circuit, the defining characteristic is that there is only one path for the current to flow. This means that the current remains consistent throughout the entire circuit, regardless of the number of components connected. Each component, such as resistors or bulbs, receives the same amount of current.

When you consider the flow of electricity in this type of circuit, it's essential to understand that since there are no alternative paths, the same electrons that leave the power source must pass through each component in turn. This results in a uniform current at every point in the circuit.

In contrast, in a parallel circuit, the current can vary across different branches, which is why that statement does not apply here. The assertion that the current is zero is incorrect since a functioning circuit must have current flowing through it. Similarly, the idea that the current breaks upon reaching a junction does not hold true in a series circuit; instead, the current flows unimpeded through all components connected in the circuit.
