Ampacity is the maximum continuous current a conductor can carry without exceeding its temperature rating. Which term describes this property?

• A. Ampacity
• B. Capacitance
• C. Impedance
• D. Inductance

Answer: (A)

Ampacity refers to the maximum continuous current a conductor can carry without its insulation overheating to the rated temperature. This property is determined by factors like conductor size, insulation type, ambient temperature, and installation conditions, and it guides how much current a wire can safely carry in operation. Capacitance describes how much charge a system can store per volt, not how much current a conductor can carry continuously. Impedance is the overall opposition to AC current (resistance plus reactance), and inductance is the ability to store energy in a magnetic field due to changing current. So ampacity is the term that describes this current-carrying capability.
