Question

Ответьте на вопросы? Conductors are materials having a low resistance so that current easily passes through them. The lower the resistance of the material, the more current can pass through it. Тhe most common conductors are metals. Silver and copper are the best of them. The advantage of copper is that it is much cheaper than silver. Thus copper is widely used to produce wire conductors. One of the common functions of wire conductors is to connect a voltage source to a load resistance. Since copper wire conductors have a very low resistance a minimum voltage drop is produced in them. Thus, all of the applied voltage can produce current in the load resistance. It should be taken into consideration that most materials change the value of resistance when their temperature changes. Metals increase their resistance when the temperature increases while carbon decreases its resistance when the temperature increases. Thus metals have a positive temperature coefficient of resistance while carbon has a negative temperature coefficient. The smaller is the temperature coefficient or the less the change of resistance with the change of temperature, the more perfect is the resistance material. 1)What are conductors? 2)What is the main function of conductors? 3)What types of conductors do you know? 4)Is there any difference between silver and copper conductors?

Answer 2

1. Conductors are materials that have a low resistance, allowing electric current to easily pass through them. They are substances that facilitate the flow of electrical charge.

2. The main function of conductors is to provide a pathway for the flow of electric current. They enable the transfer of electrical energy from a voltage source to a load resistance, allowing devices and circuits to operate.

3. There are different types of conductors, but the most common ones are metallic conductors, which include materials like copper, silver, aluminum, and gold. These materials have low resistance and are frequently used for electrical wiring and connections.

4. Yes, there is a difference between silver and copper conductors:

   • Silver is an excellent conductor of electricity and has even lower electrical resistance than copper. This means that, in terms of electrical conductivity, silver is superior to copper.

   • Copper, while not as conductive as silver, is still an excellent conductor and is much more cost-effective than silver. It is widely used in electrical and electronic applications due to its good balance between conductivity and affordability.

   In summary, both silver and copper are effective conductors, but silver offers slightly better electrical conductivity, while copper is more economically viable for most practical applications.
