Good conductors have a high resistance or low?

Good conductors have low resistance. A low resistance allows for the easy flow of electric current through the material. Materials like metals are good conductors because they have many free electrons that can move easily in response to an electric field.


Are all conductors of electricity magnets?

No, not all conductors of electricity are magnets. While some conductors like iron, nickel, and cobalt can become magnets when exposed to a magnetic field, many other conductors such as copper, aluminum, and silver do not exhibit magnetic properties.


Why can conductors conduct electricity?

Conductors, like metals, have many free electrons that are able to move easily through the material. When an electric field is applied, these free electrons can flow, allowing the conductor to conduct electricity.


Are all insulators and conductors solids?

No, insulators and conductors can be found in various states of matter. While many are solids (such as metals being conductors and plastics being insulators), there are also liquid and gaseous substances that can exhibit insulating or conducting properties.


How are thermal conductors and electrical conductors related?

Thermal conductors and electrical conductors both involve the flow of energy, but they are not necessarily the same materials. Some materials, like metals, are both good thermal and electrical conductors due to their free electrons that allow them to transfer energy efficiently. However, there are also materials that are good thermal conductors but poor electrical conductors, such as ceramics.
