Final answer:
Technical specification refers to detailed criteria for materials or products, such as the voltage and amperage of electrical outlets. Here, A (120 volt, 15 amperes outlets) is a technical specification. Calculating the current draw for multiple devices shows that the combined load will exceed the capacity of a 15-A fuse, leading to the fuse blowing.
Step-by-step explanation:
Understanding Technical Specifications and Circuit Calculation
The question asks which of the given options is a technical specification. A technical specification is a set of requirements or instructions that specifies characteristics or performance of materials, products, processes, services, or systems. In this case, option A (Outlets are to be 120 volt, 15 amperes) is a technical specification as it describes the voltage and current requirements for electrical outlets.
Current Draw and Circuit Load
When discussing the power usage and current draw of devices on a circuit, it's important to understand that the current (I) can be calculated from the power (P) and voltage (V) using the formula:
I = P / V
Toaster: I = 1800W / 120V = 15A
Electric frying pan: I = 1400W / 120V ≈ 11.67ALamp: I = 75W / 120V ≈ 0.625A
The total current draw from these devices would be the sum of their individual currents:
Total Current = Toaster + Frying Pan + Lamp = 15A + 11.67A + 0.625A ≈ 27.29A
This exceeds the rated 15-A fuse and therefore, would indeed blow the fuse.
