Question 1 of 27070

What property of a material is rated in voltage per millimeter (V/mm) of insulation thickness that the insulation can withstand without breaking down?

🔍 Key Concepts

• Electrical insulation properties and how they are measured • Difference between mechanical properties (like tensile, shear) vs electrical properties • What it means for insulation to "break down" under high voltage

💭 Think About

• Which of the listed properties directly involves how much voltage an insulating material can tolerate before it fails electrically? • Are units like V/mm typically used to describe forces, or to describe electrical stress on materials? • Which options describe resistance to physical force, and which—if any—describe resistance to electrical stress?

✅ Before You Answer

• Identify which choices are clearly mechanical properties involving force or load • Match the unit V/mm with the idea of electrical stress (volts across a given thickness) • Focus on the option that refers to the material’s ability to resist electrical breakdown rather than physical breaking
