  • Electrostatics

    Electrostatics is the study of stationary charges and the forces that are created by and which act upon these charges.

  • Proton

    A proton is a stable subatomic particle with a positive one elementary electric charge.

  • Electron

    The electron is a subatomic particle with a negative one elementary electric charge.

  • Opposite charges exert _____ forces, and like charges exert _____ forces.

    attractive

    repulsive

  • Unlike the force of gravity, which is _____, the electrostatic force may be _____ or _____ depending on the signs of the charges that are interacting.

    always an attractive force

    repulsive or attractive

  • While many of the particles we discuss in electrostatics are very, very tiny, do not forget that they still do _____.

    have mass

  • Most matter is electrically _____, as a balance of positive and negative charges ensures a _____.

    neutral

    relative degree of stability

  • Ground

    A means of returning charge to the earth

  • Static charge buildup or static electricity

    Static electricity is an imbalance of electric charges within or on the surface of a material or between materials.

  • Static charge buildup or static electricity is more significant in drier air because ...

    ...lower humidity makes it easier for charge to become and remain separated.

  • The SI unit of charge is the _____

    coulomb (C)

  • Fundamental unit of charge (in coulombs)

    e = 1.60 × 10−19 C

  • A proton and an electron each have one _____, although the proton is _____, while the electron is _____.

    fundamental unit of charge

    positively charged (q = +e)

    negatively charged (q = −e)

  • Even though the proton and the electron share the same magnitude of charge, they do not share the same _____; the proton has a _____ than the electron.

    mass

    much greater mass

  • Law of conservation of charge

    Charge can neither be created nor destroyed.

  • Insulator

    An insulator will not easily distribute a charge over its surface and will not transfer that charge to another neutral object very well—especially not to another insulator.

    An insulator will not easily distribute a charge over its surface and will not transfer that charge to another neutral object very well—especially not to another insulator.

  • On a molecular level, the electrons of insulators tend to be _____. By extension, most _____ are insulators.

    closely linked with their respective nuclei

    nonmetals

  • Experimentally, insulators serve as _____ in capacitors, as well as in _____ to prevent grounding.

    dielectric materials

    isolating electrostatic experiments from the environment

  • Conductor behavior

    When a conductor is given a charge, the charges will distribute approximately evenly upon the surface of the conductor.

    When a conductor is given a charge, the charges will distribute approximately evenly upon the surface of the conductor.

  • Conductors are able to _____ and are often used in circuits or electrochemical cells.

    transfer and transport charges

  • Conductors are often conceptualized as nuclei surrounded by _____ and are only _____ associated with the positive charges.

    a sea of free electrons that are able to move rapidly throughout the material

    loosely

  • Conductors are generally _____, although _____ solutions are also effective conductors.

    metals

    ionic (electrolyte)

  • Neutron

    The neutron is a subatomic particle which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.
