Gold, which has eight electrons in the last layer, is one of the most stable elements in nature, or difficult to react with other elements.

Gold also has good ductility, ductility or ductility is the physical properties of materials subjected to plastic deformation, no fracture or fracture under the action of charge. 

In other words, gold is an excellent raw material for making thin wires. With these properties, gold is widely used in the electronics industry to make ultra-thin orbits in microchips and to prevent contact oxidation. 

Electrical contacts that are critical to or suitable for oxidation are usually gold-plated to ensure that they are not oxidized. Silver, as the best electrical conductor in nature, is basically used for driving. 

When high frequency conduction is involved, an effect called a "skin effect" or film effect occurs, Or the film effect (referred to in technical terms as "cabista" as a "surface effect") would basically be as follows: the current AC current tends to cross the surface of the conductor and the smaller the center of the conductor, and because of this behavior.

The effective resistance of the conductor will be higher for higher frequencies, Because we will have less physical space for higher frequency current cycles but have similar "density" (compare "similar density but different frequency currents" because the two currents have the same total value, The multimeter can be measured in amperes); then we get: the higher the frequency, the greater the surface current of the driver, and the smaller the area used to pass through; because if the signal is DC or the conductor diameter is insufficient, There will only be a large current in the center of the drive. 

Therefore, where driving high frequencies are required, silver baths are usually provided in common conductors to improve the conduction of the cable or reduce its impedance.
