The copper foil is the most commonly used material for electric transformers. The copper foil is usually made up of a large number of turns of copper wire wound around a core made of magnetic material such as iron. The purpose of the core is to concentrate the magnetic field, which enhances the efficiency of the transformer. The copper wire used in the coil is usually made of high purity copper to reduce the resistance and improve conductivity.

There are several reasons why copper is the preferred material for the coil in electric transformers. Firstly, copper has an excellent electrical conductivity of around 58 million siemens per meter. This high conductivity allows the current to flow efficiently through the coil, which reduces energy loss in the form of heat. Secondly, copper is highly ductile, which means it can be drawn into thin wires without breaking. This property is critical in transformer design because the wire must be thin enough to provide a large number of turns without breaking. Lastly, copper is highly malleable, which means it can be easily formed into any shape, making it easy to manufacture the coils.
Electric transformers are essential components in the generation, transmission, and distribution of electrical energy. They operate by using the principle of electromagnetic induction, where a varying current in one coil induces a current in a second coil, which is placed in close proximity. The coils are usually made of conductive material such as copper, which is highly conductive, ductile, and malleable.
