In summary, the conversation discusses the concept of metals conducting electricity and why people aren't zapped when touching metal power pylons. It is explained that a power source and a path for electricity to flow are necessary for conductivity to occur. The person also mentions a stapler that zaps people, but it is clarified that this is due to static electricity and not a strong electrical current. The conversation also touches on the fact that some metals conduct electricity better than others, but all metals still conduct to some degree. The topic of semiconductors is also briefly mentioned.

people say metels conduct electricety but if that's true how cum metal pilons don't zap people when grounded. also i have a trick stapler that zaps people how cum its not very painfull

There needs to be a power source and somewhere for the electricity to go. When you pick up a stapler and it zaps you, that's static electricity generated by your feet, conducted through your body to the stapler. There just isn't much energy there. And I'm not sure what "metal pilons" you are talking about.

Metals do conduct electricity - that should be obvious since we use copper wire and other metals to do it. Power pylons are insulated from the power carrying cables by ceramic insulators.

so is there any metals that are poor conductors of electricetey

You have to define "poor". Conductivity varies greatly, but they still conduct. And, of course, there are the semiconductors.
 

1. Why are metals considered bad conductors of electricity?

Metals are considered bad conductors of electricity because they have a high number of free electrons that are able to move easily. However, these electrons are not tightly bound to the atoms, making it difficult for them to flow in a specific direction and carry an electric current.

2. How do bad conductors affect electrical circuits?

Bad conductors can cause resistance in an electrical circuit, which can decrease the flow of electricity and result in a decrease in the effectiveness of the circuit. This can lead to issues such as overheating and power loss.

3. Is there any benefit to using bad conductors in electrical systems?

Yes, there are benefits to using bad conductors in electrical systems. They can be used as insulators to prevent the flow of electricity, which is important for safety and for controlling the direction of the current in a circuit.

4. How does temperature affect the conductivity of metals?

Temperature can significantly affect the conductivity of metals. As the temperature increases, the atoms in the metal vibrate more, making it difficult for the free electrons to move and decreasing the conductivity. Conversely, lowering the temperature can increase conductivity.

5. Are there any exceptions to the rule that metals are bad conductors of electricity?

Yes, there are some exceptions to this rule. Some metals, such as silver, copper, and gold, have a higher number of free electrons and are therefore better conductors of electricity. Additionally, certain alloys and metal compounds can have varying levels of conductivity.
