• Electricity

  The presence of flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best known form is the flow of electrons through conductors such as copper wires.
• Electricity

  When a bunch of atoms are together and electrons are moving from one atom to the other in the same direction, this is called electricity. Electricity is the "flow of electrons". Electricity is both a basic part of nature and one of the most widely used forms of energy.
• Electrical task can be accomplished systematically to save time, effort, and resources. Most of the work cannot be done using bare hands. To do the task, electrical tools are needed to perform the job.
• Common electrical tools


  • Screwdrivers
  • Hammers
  • Pliers
  • Wire stripper
  • Electrician's knife
  • Portable electric drill
  • Hacksaw
• Screwdrivers


  • They are made of steel hardened and tempered at the tip, used to loosen or tighten screws with slotted heads. They come in various sizes and shapes.
• Types of screwdrivers


  • Standard/Flat screwdriver
  • Philips screwdriver
  • Stubby screwdriver
  • Allen screwdriver/wrench
• Standard/Flat screwdriver


  • The blade tip is wedge-shaped and resembles a negative (-) sign. This is used to drive screws with a single slot head.
• Philips screwdriver


  • This has a cross tip resembling a positive (+) sign. This is used to drive screws with cross slot heads.
• Stubby screwdriver


  • This comes in either Standard or Philips screwdriver with short shank or blade and a shorted handle used to turn screws in tight spaces where a standard screwdriver cannot be used.
• Allen screwdriver/wrench


  • This could be in the shape of a screwdriver or a wrench. Its function is to drive screws with hexagonal slot heads.
• Types of hammers

  • Claw hammer
  • Mallet (rubber head)
  • Ball-peen hammer
