Which of the following can indicate an overloaded circuit?

An overloaded circuit typically exhibits several signs that indicate its status. Fluctuating circuit voltage can suggest that the demand on the circuit is exceeding its capacity, causing voltage drops and instability as the system tries to handle the excess load. Unusual heat levels are critical indicators of an overloaded circuit, as excessive current can lead to overheating of wires and components, potentially causing damage or creating a fire hazard. Frequent circuit breaker tripping occurs as a protective response to overload conditions; the breaker is designed to disconnect the circuit to prevent damage when it senses that the electrical flow surpasses safe limits. Collectively, these signs—fluctuating voltage, unusual heat, and frequent tripping—serve as important warnings of an overloaded circuit, making it essential to address the issue to maintain safety and proper functionality within the electrical system.
