Electronic devices, particularly mobile phones, contain small quantities of gold, a highly conductive and corrosion-resistant metal. The amount present in a single handset is typically measured in milligrams, representing a minute fraction of the device’s overall weight.
The use of gold in electronics is crucial for ensuring reliable performance and longevity. Its resistance to corrosion ensures long-term connectivity within the device, and its high conductivity facilitates efficient signal transmission. Historically, gold’s unique properties have made it indispensable in various electronic applications, despite its relative scarcity and cost.
