The dry cell or Leclanche cell was the first commercial battery and therefore had a big impact on society. It is the most common and the cheapest of the commercially available cell and is most widely used in torches‚ portable radios and battery-operated clocks. It is best used for low drain appliances‚ which need only small currents such as portable items (radio). It consists of a zinc outer casting‚ the anode‚ an aqueous paste of ammonium chloride and a mixture of powdered carbon and manganese

hierarchy in society. Today‚ the meaning of ‘ethics’ is more or less equivalent to that of ‘morals’‚ which comes from the Latin word ‘mos‚ moris’ and also means custom or behaviour‚ but on a more personal level. Moralists‚ such as Nietzsche‚ Santayana and Russell‚ claim that ethical values are rather personal interpretations‚ deliberations or preferences and not general principles that can be proven true or false. John Ziman‚ the former Chairman of the Council for Science and Society‚ interprets ethics

Lead acid cells were invented in 1859 by the French Physicist Gaston Plante‚ and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg‚ but can range from half a kilogram to over 30 kilograms on the consumer market. Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries‚ their ability to supply high surge currents means that the cells maintain a large power-to-weight ratio. This makes them

only can batteries have a toxic effect on humans but if disposed of improperly they can damage water quality and wildlife. “A battery is a package of one or more galvanic cells used for the production and storage of electric energy by chemical means. A galvanic cell consists of at least two half cells‚ a reduction cell and an oxidation cell. Chemical reactions in the two half cells provide the energy for the galvanic cell operations” (Chieh‚ n.d.). Figure one shows the way the chemistry behind a

Implications of New Technologies on Organisation Technology may be broadly defined as the methods‚ procedures‚ systems‚ equipment‚ and or machines employed in producing a desired output. This may be a particular product or service. As Child‚ (2005)‚ explains organisation can be viewed as the end result of the process by which a team of people consistently put together their efforts in an orderly fashion so as to successfully reach a desired goal. New technologies have many interesting implications

other hand it comes easier to create a dystopia‚ similar to The Giver’s society. You may think that the society we live in today and a fictional dystopia are very similar‚ this is clearly not the case. While modern day society and the society in The Giver do have some similarities‚ they have many distinct differences. There are many differences between Jonas’ society and the modern day society. For example‚ in Jonas’ society people do not choose their spouses or have children. Family units are created

A potato battery is a type of electrochemical cell. An electrochemical cell converts chemical energy into electrical energy. In the potato battery‚ there is a transfer of electrons between the zinc coating the galvanized nail that will be inserted into the potato and the copper wire that will be inserted another part of the potato. The potato conducts electricity‚ yet keeps the zinc ions and copper ions separate‚ so that the electrons in the copper wire are forced to move (generate current). It’s

ABSTRACT The Batteries form a significant part of many electronic devices. Typical electrochemical batteries or cells convert chemical energy into electrical energy. Batteries based on the charging ability are classified into primary and secondary cells. Secondary cells are widely used because of their rechargeable nature. Presently‚ battery takes up a huge amount of space and contributes to a large part of the device’s weight. There is strong recent interest in ultrathin‚ flexible‚ safe energy storage
