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

PEST ANALYSIS Political- Hong Kong is politically stable‚ there would rarely be any political factors that will interrupt and slow down the company’s growth. Hong Kong doesn’t have goods and services tax so this allows McDonalds to have lower expenses and they can maximize their profit. The international operations of Mcdonald’s are highly influenced by the individual state policies enforced by each government. Economic- The economic collapse has caused Hong Kong to enter the recession stage in

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

Introduction Batteries are used every day in a variety of different devices. They allow us to charge an object and store power for later use. While batteries are a big part of daily human life they also present a challenge to society in terms of environmental sustainability. Not only do these batteries have harmful chemicals which can end up in landfills‚ but they also encourage over consumption because the more products you buy‚ the more batteries you need‚ and the more batteries must be produced
