PHY 182, Spring, 2005

Week 10

 

  Main Objectives:
  • Be able to calculate the power being dissipataed in a resistor or produced by a battery
  • Be able to explain why the potential difference between a batteries terminals is not always equal to the EMF of the battery
  • Be able to use Kirchoff's Rules to find currents and voltages in electric circuits
  • Understand how Kirchoff's rules are related to charge and energy conservation.
  • Be able to discuss qualitatively how the current and charge on the capacitor vary with time in a simple RC circuit
  • Be able to find the current in the circuit or charge on the capacitor at any time in a simple RC circuit and for either very short or very long times in a complex RC circuit
Tuesday Discuss power in a resistive circuit.  Discuss real versus ideal batteries.  Discuss Kirchoff's Rules for analyzing circuits.
