In a series circuit, as the current flows through each component, what happens to the current?

In a series circuit, the defining characteristic is that the same current flows through each component connected in that circuit. This is due to the nature of how components are arranged in a series; there are no branching paths for the current to divide into, which means the current remains constant all the way through the series.

The voltage across each component can vary depending on its resistance, according to Ohm's Law (V = I * R), but the overall current flowing through the circuit does not change value. This is a fundamental principle of circuits and is crucial for understanding how series circuits behave in electrical systems. Understanding that the current remains the same helps in troubleshooting and designing circuits effectively.
