  1. Electricity
    A form of energy that results from the interaction of charged particles such as electrons or protons.
  2. Electrostatic Series
    A list of materials that have been arranged according to their ability to hold onto electrons. 
  3. Electroscope
    • A device for detecting the presence of an electric charge.
  4. Electric Field
    A property of the space around a charged object, where the effect of its charge can be felt by other objects. For example when you rub your hair with a balloon when you bring the balloon to pieces of paper the paper will be attracted to the balloon and will move towards it. The reason for this is because of the electric field of the balloon.
  5. Electrostatic Precipitator
    A type of cleaner that removes unwanted particles and liquid droplets from a flow of gas.
  6. Insulator
    A material in which electrons cannot move from one atom to another easily.
  7. Ion
    A positively charged atom or group of atoms. 
  8. Ground
    An object that can supply a very large number of electrons, or can remove a very large number of electrons from, a charged object, thus neutralizing the object.
  9. Charging By Contact
    Generating a net charge on a neutral object by touching it with a charged object.
  10. Charging By Friction
    • A process in which objects made from different, materials rub against one another, producing a net static charge on each object.
  11. Conductor
    A material in which electrons can move easily between atoms.
  12. Induced Charge Separation
    The movement of electrons caused by the electric field of a nearby charged object that is not in direct contact with the substance.
  13. Laws of Electric Charges
    Laws that describe how two objects interact electrically when once or both are charged.
  14. Lightning Rod
    A metal sphere or point that is attached to the highest point of a building and connected to ground. For example the reason buildings in rural areas need these because lightning hits the highest part of an area and since there aren't many tall buildings in a rural area they are at greater risk of being struck.
  15. Radiation Dosimeter
    A small device that detects and measures exposure to radiation.
  16. Semiconductor
    A material in which electrons can move fairly well between atoms.
  17. Static charge
    (static electricity)
    • An electric charge that tends to stay on the surface of an object, rather that flowing away quickly.When you rub a neutral balloon on you head you create a charge on that balloon.
  18. Van de Graaff Generator
    • A device that accumulates very large charges.
