Q

What will happen to a copper wire when the current flow through the wire increases in value?

🔍 Key Concepts

• Ohm’s Law relationship between current, voltage, and resistance • How metals like copper behave when more current flows (Joule heating) • Difference between resistance, temperature, conductivity, and insulation

💭 Think About

• If you increase current in a copper wire but keep everything else the same, what physical effect happens inside the metal itself? • Which option describes something that must happen first as current increases, before damage or long‑term changes occur? • How are resistance and conductivity related—if one goes up, what happens to the other?

✅ Before You Answer

• Check which choice describes an immediate physical effect of more current, not a possible failure if you go too far • Remember that resistance of a metal generally increases with temperature, so think about which option fits that chain of events • Verify whether good conductors like copper get better or worse at conducting when they get hotter
