Electrical fruit

  1. 1. Electrical Fruits Phy 350 project *maryam ariffin *ain norin
  2. 2. AIMS
  3. 3. To observes the freshness of fruits affect on voltage and pHTo determine which fruits provide highest voltage depend on the pHTo find out which fruits can light up the bulb longest.
  4. 4. To observes the freshness of fruits affect on voltage and pHTo determine which fruits provide highest voltage depend on the pHTo find out which fruits can light up the bulb longest.
  5. 5. introduction
  6. 6. Batteries generate electricity by transformingchemical energy into electrical energy through achemical reaction between two different electrodesand one electrolyte (Giancoli, 2009). In our project we had replace batteries withdifferent type of fruits and study about their voltagereading, pH meter reading and its freshness. Fruitshave high of resistance and its not enough to light upLED.
  7. 7. Type of fruits
  8. 8. 1. lemon 2. apple3. star fruits 4. orange 5. tomato6. banana 7. potato

  15. 15. 1. The fruits is rolled2. The fruits is cut and then, Zn and Cu are placed3. The multimeter is connected to the fruit4. A reading is recorded
  16. 16. 1. The fruits is rolled2. The fruits is cut and then, Zn and Cu are placed3. The multimeter is connected to the fruit4. A reading is recorded5. The multimeter is placed with LED and observation is recorded
  17. 17. 1. The fruits is rolled2. The fruits is cut and then, Zn and Cu are placed3. The multimeter is connected to the fruit4. A reading is recorded5. The multimeter is placed with LED and observation is recorded6. The fruit is removed and blended
  18. 18. 1. The fruits is rolled2. The fruits is cut and then, Zn and Cu are placed3. The multimeter is connected to the fruit4. A reading is recorded5. The multimeter is placed with LED and observation is recorded6. The fruit is removed and blended7. The pH is taken and recorded
  19. 19. 1. The fruits is rolled2. The fruits is cut and then, Zn and Cu are placed3. The multimeter is connected to the fruit4. A reading is recorded5. The multimeter is placed with LED and observation is recorded6. The fruit is removed and blended7. The pH is taken and recorded8. The steps is repeated

  27. 27. conclusion
  28. 28. Is that the freshness of fruits affect the voltage and pH?
  29. 29. Is that the freshness of fruits affect the voltage and pH?
  30. 30. Is that the freshness of fruits affect the voltage and pH? Voltage will change either becomehigher or lower depend on the changes of citric acid in fruits (pH)
  31. 31. Is that the freshness of fruits affect the voltage and pH?pH will change either become more acidic or less depend on the decomposition process
  32. 32. Which fruits provide highest voltage depend on pH?
  33. 33. Which fruits provide highest voltage depend on pH?
  34. 34. Which fruits provide highest voltage depend on pH?Theory state:The more acidic will provide more voltage
  35. 35. Which fruits provide highest voltage depend on pH?
  36. 36. Which fruits provide highest voltage depend on pH?
