Diode question

  1. May 8, 2009 #1
    1. The problem statement, all variables and given/known data
    A diode with reverse saturation current of 1pA and an ideality factor of 1.15 is connected in series with a resistance of 200ohms and connected to a 5V DC supply voltage. Find the current flowing in the diode at a temperature of 290K? How does the current change when a 800ohm resistance is placed in parallel with the diode?

    2. Relevant equations



    3. The attempt at a solution

    Well you could start off by providing the equation for current flow I_D in a diode.
