What happens when a circuit experiences overload?

• A. The flow of electricity is enhanced
• B. The circuit continues to operate without issues
• C. The circuit may be damaged or cause fires
• D. The circuit automatically increases resistance

Answer: (C)

When a circuit experiences an overload, it draws more current than it is designed to handle. This excessive current can lead to overheating of the wires and components within the circuit, potentially causing damage. In severe cases, the increased heat can ignite surrounding materials, resulting in fires. The significance of this outcome underscores the importance of circuit protection devices, such as fuses or circuit breakers, which are designed to interrupt the current flow and prevent such hazards when an overload occurs. Understanding this risk is crucial for safe electrical system design and operation.
