Presentation Transcript

  1. Interactions of Charge Centers

  2. Basic Electrical Relationships Coulomb’s Law Coulomb -- a unit of charge 1 coulomb = 6.2×1018 elementary charges The electrical analog of force is voltage The electrical analog of velocity is current

  3. Electrical Potential

  4. Movement of Charges A good analogy is the expansion of gases into larger containers -- although the proximate cause of the expansion is quite different!

  5. i = e * G A Purely Resistive Circuit Which way does the current flow?

  6. Series and Parallel Resistive Circuits Can you draw an analogy to these circuits using water flow?

  7. Capacitance Energy storage -- the electrical analog of elasticity

  8. A Purely Capacitive Circuit

  9. Equilibrium in a capacitive circuit

  10. An RC Circuit

  11. The Time Constant, t A measure of the time needed to charge an RC circuit. t = RC
