🔍 Key Concepts

• Resistance vs. conductivity in metals • How temperature affects resistance • What property of a material makes it a good electrical conductor

💭 Think About

• Which option talks about offering little opposition to electric current, and how does that relate to resistance? • Does a shiny or polished surface automatically mean better electrical conductivity? • Think about why copper wires are used inside cables—what property of copper is most important for carrying current efficiently?

✅ Before You Answer

• Identify which choice best describes low electrical resistance. • Eliminate choices that focus on mechanical or cosmetic properties instead of electrical properties. • Check that the correct choice directly relates to how easily current flows through the material.
