What is a potential consequence of overloading an electrical circuit?

Overloading an electrical circuit occurs when the demand for electricity exceeds the circuit's capacity to safely handle it. This excess load generates additional heat within the wiring and connected devices, which can lead to insulation failure and expose wires. Over time, this overheating can compromise the integrity of the electrical components, potentially leading to a short circuit or even a fire.

The other options do not reflect the realities of electrical circuit behavior under overload conditions. Improved electrical efficiency and enhanced electrical performance are not outcomes of overloading; rather, they pertain to systems functioning within their designed parameters. Increased power consumption can accompany increased load, but it does not directly describe the grave risks associated with circuit overload, such as the potential for overheating and fire.
