C. 25
D. 20
percent of its rated power.
Answer (2)
AC equipment operates within a certain percentage of its rated voltage.
The question asks to select the best answer for the maximum allowed percentage deviation from the rated voltage.
Considering the options, 10% is the most reasonable and commonly accepted value for voltage tolerance in AC equipment design.
The best answer is \boxed{A}.
Explanation
Understanding the Problem The question asks about the voltage tolerance range within which AC equipment is designed to operate. We need to select the most appropriate percentage from the given options.
Analyzing the Options The options are 10%, 15%, 25%, and 20%. AC equipment is generally designed to operate within a certain percentage of its rated voltage to ensure proper functioning and prevent damage.
Selecting the Best Answer Considering the options, 10% and 20% are common tolerance ranges for electrical equipment. However, 10% is a more standard and widely accepted value for AC equipment voltage tolerance.
Final Answer Therefore, the best answer is 10%.
Examples
Understanding voltage tolerance is crucial in electrical engineering. For example, when designing a power supply for a sensitive electronic device, engineers must ensure that the voltage remains within a certain percentage of the specified value. If the voltage fluctuates too much, it can cause the device to malfunction or even be damaged. Knowing the standard voltage tolerance ranges helps engineers select appropriate components and design robust systems that can handle voltage variations without compromising performance or safety. This ensures the reliable operation of electrical equipment in various applications.
AC equipment is designed to operate within a certain percentage of its rated voltage, typically around 10%. This percentage allows for safe and reliable function despite variations in the power supply. Therefore, the best answer to the question is option A, which is 10%.
