uses were wrought from copper by early civilizations. The craftsmen who built the great pyramid for the Egyptian Pharaoh Cheops fashioned copper pipe to convey water to the royal bath. A remnant of this pipe was unearthed some years ago still in usable condition, a testimonial to copper's durability and resistance to corrosion.
Copper loss is the term used to describe the energy dissipated by resistance in the wire used to wind a coil. In 99.9% of cases this wire will be made of copper, whose resistivity at 20°C is about 1.73 × 10 –8 Ω m. However, coils often have to operate above room temperature and will be heated by the operating losses in any case.
