  • 1. Electricity & Magnetism
    By: John Smith
    Christopher Dale
  • 2. Electrostatics
    Is the study of the interactions between electric charges that are not moving.
  • 3. Electrostatics deals with things such as…
    charges
    conservation on electricity
    electric fields
    electrical potential
    and electrical potential difference
  • 4. Charges
    with charges there are two types:
    positive = Lost electrons
    Negative = Gained electrons
  • 5. Law of conservation of electric charges
    states that all of the electric charge in any process is zero
    there is also coulombs(C) (F=k(Q1Q2/r2) which shows change of charges.
  • 6. Electric fields
    They exist in the space around the charged particle
    it is represented by lines that start on a positive charge and end on a negative charge.
    to test the force exerted on a charged particle in an electric field and uses the equation E=kQ/r2
  • 7. Electrical potential
    is a point that equals the electric potential energy per unit charge placed at that point.(V=PE/Q)
    and the electrical potential due to a point charge (V=kQ/r) and as r approaches infinity V=0
  • 8. Gauss’s law
    was created by Karl Friedrich Gauss
    Related to electric charge and electric field and is more general version of Coulomb’s law.
    involves the concept of electric flux which is an electric field passing through a given area.
    equation: Φ=EA(cos(θ))
  • 9. Electrical potential differance
    the amount of work required to move a charge from point a to point b
    equation: V-V=-W/q
    fields and electrical potential are similar in that they both show the effects of any charge distribution but electric field is a vector and electrical potential is a scalar.
