What’s the difference between resistance and resistivity? Resistance is the obstruction offered to the flow of current by a conductor. Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor. So basically‚ resistance is the property of the object (say a copper wire)‚ whereas resistivity is the property of the substance (copper). And so resistance depends upon the properties of the object. Whereas resistivity depends upon the properties of the metal.

Cady Crofoot Noah Tysick English 110 March 25‚ 2013 Electronic Mourning Technology is unquestionably not a new concept in this modern day society. Almost every business that a customer walks into is run by technology in some way. A business that most do not relate to technology though‚ is the funeral home industry. Of course people don’t enjoy visiting funeral homes and facing the death of a loved one and the potential high costs that can go with laying them to rest. Funerals are no longer

A light-emitting diode (LED) is a semiconductor light source.[6] LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Appearing as practical electronic components in 1962‚[7] early LEDs emitted low-intensity red light‚ but modern versions are available across the visible‚ ultraviolet‚ and infrared wavelengths‚ with very high brightness. When a light-emitting diode is switched on‚ electrons are able to recombine with holes within the device‚ releasing energy

However‚ at this time there is still a grey area of information about the effects‚ it is unclear whether E-cigarettes may be effective to help people quit smokeing and be used as a cigarette quitting aid. There is also the possibility that they could perpetuate the nicotine addiction and thus interfere with quitting. A lot is to come in the future about the dangers of this product since it is a relatively new invention‚ information is still to come on the use
