What can result from overloading an electrical circuit?

• A. Increased efficiency
• B. Tripped breakers or blown fuses
• C. Improved conductor integrity
• D. Enhanced system longevity

Answer: (B)

Overloading an electrical circuit typically leads to the occurrence of tripped breakers or blown fuses. This is a protective mechanism designed to prevent overheating and potential electrical fires. When the demand for current exceeds what the circuit can safely handle, the excessive current flow generates heat within the circuit components, such as wiring and connectors. Circuit breakers are designed to detect this overload condition and will trip, interrupting the electrical flow to prevent further damage. Similarly, fuses serve a similar purpose, melting to break the circuit when excessive current flows through them, thus protecting the system from overheating and potential fire hazards. The other options do not reflect the outcomes of circuit overload: increased efficiency and improved conductor integrity are unlikely as overload typically harms equipment, while enhanced system longevity is not typically achieved under conditions of overload.
