No. A thermocouple is made from two dissimilar wires. At the junction of these two wires, an electrical signal is generated that is measured in millivolts. If you insert another type of wire, such as copper, then you have introduced another electrical junction. Your signal will be (millivolt from junction 1 + millivolt from junction 2).

Maybe. A thermocouple measures the temperature difference between the sensing junction (where the two different metal wires meet) and the other end of the wire, the reference junction. If you extend a thermocouple with copper wire, you will measure the temperature difference between the junction and the location where the copper extension is spliced on. If the copper splice is the same temperature as the reference junction, or if you can measure the temperature at the splice, then it will be fine. In general, it is better to run the thermocouple wire to the reference junction.

How is copper losses reduced in transformers?
how to reduce copper losses in a transformer Copper losses are due to the resistance of the copper (or aluminum) windings. To reduce copper losses the transformer would have to be rewound with heavier gage wire.
What are telephone wires made of?
Mainly all telephone wires are made of copper with a plastic coating for insulation. Older form of telephone wire had a paper or pulp insulation over the copper wire. They are also a twisted pair cable.
Does a thermocouple have to touch at the tip or sides to operate correctly?
All thermocouples (whether type J, type K, type T, etc.) measure the difference in temperature between the Tip (junction between two different metals), and the other end of the thermocouple wire, often referred to as the "cold junction." There must be two such junctions somewhere for the thermocouple to operate correctly; typically the measurement junction is at the tip. To measure the temperature of some thing, try to put that junction as close as possible to that thing. However, since the thermocouple is metallic and the measurement relies on detecting tiny voltages, connecting the tip electrically to a metallic surface could affect the measurement. For that reason thermocouples often have insulated tips.
How can a copper wire b silver on the outside?
Its probably not silver. Its probably tin plated to make it easier to solder.
What is amp rating of 14 gauge wire?
In normal residential use it is 20 Amps. That depends on alot of things such as the wire insulation, ambient temperature, etc. Standard NM 12/2 (Romex or equivalent, which is likely what you are asking as it is the primary type used to wire residential) is rated for 20 amps, 14 gauge is 15 amps, 10 gauge is 30 amps.
Which materials could you use to create a thermocouple?
To create a thermocouple one needs thermocouple wire, a means of spot welding the wire, and wire strippers. A thermocouple is used to measure temperature.
Do you need to use TC extension wire to connect a thermocouple or can you use shielded cable?
You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.
What is heavy copper wire used for?
Heavy copper wire is used for heavy current loads.
Can Recycled copper used for copper wire?
yes
How do you refine copper wire scraps?
To refine copper wire scrap, you need professional tools and equipment such as copper stripper which is used for removing insulation from copper wire.
What is the metal used in wire?
In most cases, copper is the metal used in wire.
Is copper wire the same as thugsten wire?
Copper wire and tungsten wire are not the same. Copper wire is made of copper and is a good conductor of electricity, while tungsten wire is made of tungsten and is used in applications where high melting points and durability are required. Tungsten wire is often used in industrial applications and light bulb filaments.
What is the difference between copper bare and copper millberry wire?
Copper bare wire refers to uninsulated copper wire that has not been processed, while copper millberry wire is clean, untinned, uncoated, and unalloyed copper wire that is at least 99.9% pure. Millberry wire is typically used for high-quality applications like electrical wiring due to its purity and consistency, while bare copper wire is more commonly used for grounding applications.
What elements are used in wire?
Usually copper.
Why copper is used in electricity?
Copper is used in electical equipment and wire as it is a good and cheap conductor
What is the chemical name of copper wire?
Copper. The wire is made of elemntal copper not a chemical compound. (Note the copper used may sometimes be alloyed with another metal or occasionally be a solid solution of small amounts of oxide in the pure metal. This improves the durability and handling characteristics of the wire.)
How much platinum in thermocouple wire?
Thermocouple wires typically contain a small percentage of platinum, usually less than 10%. The exact amount of platinum in a thermocouple wire will vary depending on the specific type and manufacturer of the wire.
