In a series circuit, what happens if one component fails?

• A. The circuit remains operational
• B. The current increases
• C. The entire circuit stops functioning
• D. The resistance decreases further

Answer: (C)

In a series circuit, all components are connected in such a way that there is a single path for the current to flow. This means that the current must pass through each component sequentially. If one component fails—such as a resistor or a light bulb—the path for that current is broken. Since the current cannot bypass the failed component, it results in the entire circuit ceasing to function. Therefore, the correct answer indicates that the failure of one component disrupts the entire circuit, causing it to stop operating altogether. The nature of a series circuit is fundamentally different from a parallel circuit, where a failure in one branch does not affect the operation of others. Understanding this concept is crucial for analyzing and troubleshooting electrical circuits in both amateur radio applications and broader electrical contexts.
