Young Dark Blonde Girl With A Silver Necklace And Pendant Reveals Her Pink Lace Lingerie And Black Hold-ups In The Bed At Home

Some electrical and electronic products use silver for its superior conductivity, even when tarnished. The primary example of this is in high quality RF connectors. The increase in conductivity is also taken advantage of in RF engineering at VHF and higher frequencies, where conductors often cannot be scaled by 6%, due to tuning requirements, e.g.cavity filters. As an additional example, printed circuits and RFID antennas can be made using silver paints, and computer keyboards use silver electrical contacts. Silver cadmium oxide is used in high voltage contacts because it can withstand arcing.
Some manufacturers produce audio connector cables, speaker wires, and power cables using silver conductors, which have a 6% higher conductivity than ordinary copper ones of identical dimensions, but cost very much more. Though debatable, many hi-fi enthusiasts believe silver wires improve sound quality.
Small devices, such as hearing aids and watches, commonly use silver oxide batteries due to their long life and high energy to weight ratio. Another usage is high-capacity silver-zinc and silver-cadmium batteries.
