Name any four insulators.
Answers
Glass, air, plastic, rubber, and wood are all popular insulators.
An electrical insulator is a substance that prevents electric current from flowing freely. The electrons in the insulator's atoms are closely bonded and cannot easily travel. Other materials, semiconductors, and conductors are better at conducting electric current. The resistivity of an insulator differentiates it from semiconductors or conductors; insulators have a greater resistance than semiconductors or conductors. Non-metals are the most prevalent examples.
Answer:
1. Some common insulators are glass, air, plastic, rubber, and wood
2. Insulators are used to protect us from the dangerous effects of electricity flowing through conductors.
3. Sometimes the voltage in an electrical circuit can be quite high and dangerous.
4. An electrical insulator is a material in which electric current does not flow freely.
