Question 1 Report
Fig. 11 shows a coil of wire used for electrical wiring. The item shown is commonly used in design and technology projects. It has been designed and manufactured to meet specific requirements. The choice of materials and construction methods affects the quality of the finished product.
It can be fixed if it breaks. The lid lifts up and down.
It is made from steel. The parts are joined with joints. Each part has a clear job to do.
The surface of the acrylic can be improved by applying a wax. Ergonomic factors have influenced the shape and dimensions of the design.
Name the metal used to make the wire shown in Fig. 11.
Answer Details
The metal used to make the electrical wire shown in Fig. 11 is copper. [1] Copper is the standard metal for electrical wiring because it is an excellent electrical conductor, meaning electricity flows through it with very low resistance. This efficiency reduces energy losses as heat and ensures reliable delivery of current. Copper is also ductile, so it can be drawn into thin wires without breaking, and it is malleable, allowing the wire to be bent and routed around corners and through conduits during installation. Additionally, copper has good resistance to corrosion, so the wire maintains its conductivity and integrity over a long service life.
