Current and Voltage Relationships

Click For Summary
SUMMARY

The discussion focuses on the current and voltage relationships in various systems: filament lamps, semiconductor diodes, metal conductors at constant temperature, and copper (II) sulfate solutions with electrodes. The user seeks guidance on experimental procedures, particularly for semiconductor diodes and copper (II) sulfate solutions. Key experimental steps include applying voltage and measuring current, with specific considerations for temperature control in metal conductors and bidirectional measurements for diodes and solutions. Additionally, the user inquires about the differences in polarization between dry cells and Leclanché cells.

PREREQUISITES
  • Understanding of Ohm's Law and basic electrical principles
  • Familiarity with semiconductor physics and diode characteristics
  • Knowledge of electrochemistry, particularly regarding copper (II) sulfate solutions

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.
