Computer monitors are typically packed into low stacks on wooden pallets for recycling and then shrink-wrapped. [1]Electronic waste recycling, electronics recycling, or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics; when referring to specific types of e-waste, the terms like computer recycling or mobile phone recycling may be used.
[citation needed] Electrical waste contains hazardous but also valuable and scarce materials. Up to 60 elements can be found in complex electronics. [ 23 ] Concentration of metals within the electronic waste is generally higher than a typical ore, such as copper, aluminium, iron, gold, silver, and palladium. [ 24 ]
The directive imposes the responsibility for the disposal of waste electrical and electronic equipment on the manufacturers or distributors of such equipment. [5] It requires that those companies establish an infrastructure for collecting WEEE, in such a way that "Users of electrical and electronic equipment from private households should have the possibility of returning WEEE at least free of ...
[112] [113] Digitunity is a non-profit organization that aims to collect used devices to donate it to those in need. [112] The World Computer Exchange accepts computer donations of electronics that they give to low-income communities worldwide. [113] Free Geek is a collectively run, non-profit organization based in Portland, Oregon. It aims to ...
A US National Electrical Code rule for the number of circuits in a panel board. clamp meter An ammeter that measures current with a split core that can be clamped on a wire. Clapp oscillator An electronic oscillator circuit that uses three capacitors and an inductor. class of accuracy in electrical measurements
Sources of electrical power: Battery – acid- or alkali-based power supply. Fuel cell – an electrochemical generator; Power supply – usually a main hook-up; Photovoltaic device – generates electricity from light; Thermoelectric generator – generates electricity from temperature gradients; Electrical generator – an electromechanical ...
A Leyden jar (or Leiden jar, or archaically, Kleistian jar) is an electrical component that stores a high-voltage electric charge (from an external source) between electrical conductors on the inside and outside of a glass jar. It typically consists of a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal ...
Energy harvesting (EH) – also known as power harvesting, energy scavenging, or ambient power – is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, also known as ambient energy), then stored for use by small, wireless autonomous devices, like those used in wearable electronics, condition ...
