Current and Voltage Relationships

[perjogab]

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?

THANKS

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.
