Electricity & magnetism

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