Electrical wiring needs to be made of two main materials: a good conductor of electricity, usually copper, and - to prevent the wires inside a cable from connecting to one another - a very good insulator, usually pvc (poly-vinyl-chloride) or special rubber.
Cables used for special scientific or military uses may use silver or gold for their wires even though they are very expensive compared to copper.
Aluminum is a cheaper alternative to copper, silver or gold. Aluminum is a much lighter and cheaper material to use as a conductor but you must give up some amperage versus a cable that is the same size, but made from copper, because aluminum is not such a good conductor.
copper is used for conductors, plastics are used for insulation, steel is used for conduit
What else can I help you with?
What is the significance of the conductivity tensor in the field of materials science and how does it influence the electrical properties of materials?
The conductivity tensor is important in materials science because it describes how materials conduct electricity in different directions. It influences the electrical properties of materials by determining how easily electricity can flow through them, which is crucial for designing electronic devices and understanding the behavior of materials in various applications.
What are the two examples of electrical materials that are insulators?
Two examples of electrical materials that are insulators are rubber and glass. Insulators are materials that do not conduct electricity well and are commonly used to protect against electrical shocks or to prevent the loss of electrical energy.
What is it called when The rubber and glass rods that are used in electrical demonstration are examples of materials through which charges will not move easily?
The rubber and glass rods are examples of insulators, which are materials that do not easily allow charges to move through them. This property makes them useful in electrical demonstrations to show the behavior of charges in different materials.
Why do electric discharges occur?
Electric discharges occur when there is a buildup of electrical charge in a material or between two materials with different electrical potential. When the electrical resistance is overcome, the stored charge is released in the form of a spark or visible discharge.
What is non isotropic materials?
Non-isotropic materials are those that exhibit different properties in different directions. This means that the material's characteristics, such as strength, thermal conductivity, or electrical conductivity, vary depending on the direction in which they are measured. Anisotropic materials are common in various applications, such as composites, crystals, and wood.
What are the different electrical materials?
There are many different types of electrical materials most of which are types of metals. The most common electrical material is copper.
What type of electrical supplies would a handyman need?
There are several different electrical supplies that can be used by a handyman. These can include an electric drill to an electric saw.
