Electricity Test Review Questions

• Describe each part of an atom.

  • Prorton : A positvely charged particle found in the nucleus of an atom.
  • Neutron : A no charge particle found in the nucleus of an atom
  • Elecron : A negativley charged particle found around an atom
  • Nucleus : The centre of an atom which has particles found in it such as Protons and Neutrons.
• What is electricity?

  Electrictity is a form of energy. On top of that electrical energy, comes from small particles called atoms. Lastly, when one atom transfers Electrons to another atom the flow of electrons is what creates the electricity.
• Volts - The amount of pressure being created from the source of electricity

  Ohms - The resistance which is directly related to the width of the line or wire

  Amps - The amount of electricity flowing though a line at any given position

  Watts - The overall amount of electricity.
• What is a series circuit?

  A series circuit is when the path of electricity has only one possible way of flowing thought the circuit. To sum up, there are no alternate routes.
• What is a parrallel circuit?

  A parrallel circuit is when the path of electricity has more than one possible way of flowing though the circuit. To sum up, there are various alternate routes.
• What ia an insulator?

  Material that does not easily allow the flow of electricity. ( e.g eraser, silicone, plastics, rubber and paper.
• What is a conductor?

  A material that allows electricity to flow through it. ( e.g metal paperclip, zippers, silver, gold, steel and iron.
• Whats a polar device?

  A polar device is when something is connected one way, a certain thing will happen. However, when connected in a different way, a different thing happens.
• Whats the difference between a DC current and an AC current?

  DC is when a current flows in one direction. AC is when theres more than one direction.
• Whats the difference between current electricity and static electricity?

  Stactic electricity is caused by a buildup of negative charges in one place and postive charges in another place. Current electricity is caused by the flow of electrons which we are most accustomed to.
