Which is a common sign of an electrical overload?

  1. Tripped circuit breakers

  2. Low resistance readings

  3. Consistent power flow

  4. Steady voltage levels

The correct answer is: Tripped circuit breakers

A common sign of an electrical overload is tripped circuit breakers. When too much current flows through a circuit, the breaker automatically shuts off to prevent damage or fire hazards. This safety mechanism is designed to protect electrical systems and appliances from overheating and potentially harmful situations. In contrast, low resistance readings might indicate an electrical issue, but they are not specific to overload conditions. Consistent power flow and steady voltage levels typically suggest that the electrical system is operating normally and is not experiencing overload. These conditions could mask underlying problems, but they do not directly indicate an overload situation like tripped circuit breakers do.
