Electronic waste From Wikipedia‚ the free encyclopedia For the EC directive‚ see Waste Electrical and Electronic Equipment Directive. Defective and obsolete electronic equipment. Electronic waste‚ e-waste‚ e-scrap‚ or waste electrical and electronic equipment (WEEE) describes discarded electrical or electronic devices. There is a lack of consensus as to whether the term should apply to resale‚ reuse‚ and refurbishing industries‚ or only to product that cannot be used for its intended purpose

Assignment no. 2 Ujjwal Dahiya Electronic sensors Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter (for example: temperature‚ blood pressure‚ humidity‚ speed‚ etc.) into a signal which can be measured electrically. Classification based on property is as given below: Temperature - Thermistors‚ thermocouples‚ RTD’s‚ IC

A fax machine is a device that can send a copy of a paper document over the telephone network. The sending fax converts the light/dark areas of the printed document into noises. These noises travel through the phone system and are received by another fax machine. The receiving fax machine converts the noises into printed

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

digital electronic is the branch in which most of the devices used work on direct current. this current is very less as compared to the current used in electrics. The direct current is more dangerous as compared to the altenating current‚ but it is harmful after a certain range like above 18 volts. But all the electronics appliances work below this range . The main things in digital electonics are 0 and 1.The whole of the digital electronics depends on 0 & 1. where o stands for ’off’ and 1 for

Electronic Waste The mishandling of electronic waste also referred to as E-Waste‚ has lasting environment and social impacts on underdeveloped and struggling countries that become dumping grounds for unwanted and nonworking electrical and electronic components and devices. Many of the electronic-waste recycling facilities are located in South and East Asia. E-waste is a source of electronic parts and valuable metals for reuse. This industry is only profitable in Asia‚ because laborers work for

ELECTRONIC MEDIA Electronic media are media that use electronics or electromechanical energy for the end user (audience) to access the content. This is in contrast to static media (mainly print media)‚ which are most often created electronically‚ but don ’t require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to the general public are better known as video recordings‚ audio recordings‚ multimedia presentations‚ slide presentations
