Resistivity figures are often specified for copper and aluminum wire, in ohms per kilometer. High temperature and resistance material. Resistance depends on the material the wire is made of. A comprehensive introduction to electricity, including current, insulators and conductors. CCA is cheaper and lighter, at the expense of somewhat higher resistance (about the same as copper two AWG numbers up). Many RTD elements consist of a length of fine wire wrapped around a ceramic or glass core but other constructions are also used. Now, the unknown resistance can be calculated as, The specific resistance or resistivity of the material of the wire can be then calculated by using the relation, ; Where L be the length of the wire and r be its radius. The resistance temperature detector, or the RTD, is a sensor whose resistance changes with temperature.Typically built of a platinum (Pt) wire wrapped around a ceramic bobbin, the RTD exhibits behavior which is more accurate and more linear over wide temperature ranges than that of a thermocouple.
