alleryStart learning →A material whose resistance is so high that no current flows through it is called
AConductor such as copper and silver
BInsulator such as glass and rubber
CSemiconductor such as silicon and germanium
DSuperconductor at very low temperature
Answer & Solution
Correct answer: B. Insulator such as glass and rubber
1. The chapter classifies materials by their conductivity.
2. Conductors carry current easily.
3. Insulators block flow because their resistance is very high.
4. So option A is correct.
