Silver is a good conductor of electricity but also has low electrical resistance, making it an effective choice for reducing energy loss in metal wires. It has high thermal conductivity, allowing it to dissipate heat efficiently, and resists oxidation, ensuring long-term performance as an insulator.
What else can I help you with?
Why is silver produced when a copper wire and silver nitrate a put together?
When a copper wire is placed in a silver nitrate solution, a redox reaction occurs. Copper atoms from the wire lose electrons to form copper ions in the solution, while silver ions gain electrons to form solid silver. This leads to the deposition of silver metal on the surface of the copper wire.
Is copper wire a condutor or insulator?
Copper wire is a conductor of electricity. Its high conductivity allows electric current to flow easily through it.
Why is copper not a good insulator for a metal wire?
Copper is not a good insulator because it is a conductor of electricity, allowing electric current to flow through it easily. Insulators, on the other hand, have high resistance to the flow of electricity. This is why copper is commonly used as a conductor in electric wires instead of an insulator.
You have copper and silver speaker wire and the silver has writing on it Which one is positive?
The copper wire is typically positive. However, the best way to determine which is positive and negative is by referring to the user manual or guide that came with the speakers. The writing on the silver wire is likely there to indicate which wire is positive.
How do you extract silver from silver nitrate?
Dissolve the silver nitrate in water (a one molar solution [17 grams per litre of water] is best). There are two paths: pure metal substitution or complex ion replacement. Pure metal: Place a more active metal (such as copper wire or aluminum foil) in the silver nitrate solution and let the oxidation-reduction reaction occur. The more active metal will replace the silver in solution, causing the silver to crystilize on the new material. Complex ion replacement: Add ammonia to the silver nitrate solution in a 1:3 ratio. Stir until the precipitate redissolves. Add about 5 more millilitres of ammonia. This is known as the Tollen's Reagent. Add a dilute solution of glucose to the Tollen's Reagent and heat in a 70 degree celsius water bath. A mirror will form on the inside of whatever container you used (this can be scrapped off, and is slightly more pure than the metal replacement). ~James
What is the best insulator for metal wire?
A wire is a conductor. It is usually coated with an insulator to isolate the current flowing in the conductor portion of the wire from other things around the wire, like your hand.
Why is glass the best insulator for metal wire?
Glass has excellent insulation characteristics
What is a good insulator for a metal wire?
A good insulator would be rubber or plastic.
What type of metal is the best electrical conductor but is not used in wire?
silver
Is wire an insulator or conductor?
Wire can be either an insulator or a conductor, depending on its material and properties. Copper wire, for example, is a good conductor of electricity, while rubber-coated wire is used as an insulator to protect against electric shocks.
What terms describe the metallic core of a wire?
conductorThe core of a wire is the center, the metal part. And insulator is the wrapping on the outside, and it makes sure that the electricity doesn't harm you. Electricity must have a conductor to work, and metal is an excellent conductor.
Is a key an conductor?
It is a conductor. Most keys are made of metal, and Metal is one of the best conductors in existence. A conductor being something that accepts electricity, such as a copper wire, and an insulator something that doesn't let it through, such as rubber.
Is a pipe cleaner a insulator and a conductor?
it makes a good conductor because it is steel, but not so great as an insulator. this is simply because there is space between the fibers on the outside, and that something could come in contact with the steel wire.
Is a plastic coating on wire a conductor or an insulator?
insulator
Is steel spoon is conductor or insulator?
A steel spoon is an excellent conductor of heat.ANSWER: Conductor
Is a key a insulator or a conductor?
A metal key would conduct electricity.
