Homework Help: Current and Voltage Relationships

  1. Nov 26, 2008 #1
    I am trying to find out about the relationship between current and voltage in:
    a) filament lamps
    b)semi-conductor diodes
    c) a metal conductor at constant temperature
    d) a solution of copper (II) sulphate using electrodes.

    I pretty much know the results I am supposed to get, but could anyone aid me in steps for conducting experiments; especially for the semi-conductor diodes and the solution of copper (II) sulphate using electrodes.

    Lastly, what is the difference between polarization in a dry cell and in a leclanche cell?

    The experimental setup for each of these cases is pretty much the same, isn't it? You apply a voltage and measure the current. Of course for b and d you have to do this in both directions and for c you have to find a way to keep the temperature constant.

    I got what I needed but thanks for the quick reply.
