Materials that do not allow electric current to pass through them are called _______.
Answer & explanation
Correct answer: option 2
The correct answer is option 2. insulators.
Materials that do not allow electric current to pass through them are called "insulators."
When electricity passes through insulators, it encounters a significant amount of resistance, and as a result, very little or no current can pass through.
Common examples of insulators include:
- Rubber
- Glass
- Plastic
- Porcelain
- Wood
- Air (under certain conditions)
