2
New cards

Q: What is an insulator?

A: A material that resists electron flow.

3
New cards

Q: Why do metals conduct electricity well?

A: They have free-moving electrons (low resistance).

4
New cards

Q: Why don’t insulators conduct electricity?

A: Their electrons are tightly bound and can’t move.

5
New cards

Q: Why does a copper rod not hold a charge?

A: The electrons flow through it and into the ground.

6
New cards

Q: What happens when a metal object is held with an insulating handle and charged?

A: The charge spreads evenly through the conductor.
