A wire has to be made of a conducting metal such as copper or aluminium, and it has to be thick enough to carry the required amount of electric current. Wire is often given an enamel coating to insulate it
Wires are often stranded which gives flexibility.
The gauge of a wire is related to its cross sectional area and therefore defines its current carrying characteristics.
Acetal enameled wire, with two thermal grades of 105 and 120, has good mechanical strength
Glass has excellent insulation characteristics
Sure some resistors are wire wound chrome wire and as such will display an inductance characteristics
No, copper wire is not a mixture; it is a pure substance made primarily of copper metal. Copper has distinct physical and chemical properties, and when drawn into wire, it retains its metallic characteristics. Any impurities present in the wire would be minimal and would not classify it as a mixture.
An ideal wire for electrical conductivity should have low resistance, high conductivity, and be made of a material that is durable and can withstand high temperatures. Additionally, the wire should be flexible and easy to work with for installation purposes.
Yes, the color of iron wire is a physical property. Physical properties are characteristics of a substance that can be observed or measured without changing the composition of the substance, and the color of iron wire is one such observable characteristic.
The American Wire Gauge (AWG) is a shorthand way to identify key characteristics of the size of a wire and pertinent specifications associated with the size. So you will often hear someone ask what gauge wire do I need for a 15 Amp circuit in my home. The shorthand answer in this case would be 14 AWG for a typical residential wiring job.
Normally aluminum, zinc, copper, or an alloy that will provide predictable characteristics and blow under the conditions the fuse was designed for.
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.)
If the electrical characteristics of the wire itself are not part of the experiment, then the wire should be thick and short. This minimizes both the resistance and inductance of the wire, and therefore the chances that the effects of the wire could influence the observations of the experiment.
The red wire is the positive wire. The black wire is the ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
