SUMMARY

The discussion focuses on the conductance of a graphite-coated paper strip, specifically a strip measuring 10mm in width and 250mm in length with a resistance of 2kΩ. The user seeks to determine the dimensions for a strip that achieves a conductance of 1mA/V. It is clarified that conductance decreases with increasing length and increases with increasing width, correcting the user's initial misunderstanding regarding the relationship between resistance and conductance.

PREREQUISITES
  • Understanding of electrical conductance and resistance
  • Familiarity with Ohm's Law and its applications

I have this question whihc is confusing me on Conductance. The Question is Paper uniformly coated with graphite can be electrically conducting. A strip of the coated paper is 10mm wide and 250mm long has a resistance of 2KO (ohms). Sggest dimensions for a strip with conductance 1mA V-1 (little -1 above V, sorry can't remember the name for that :frown: )

Okay this is what I know already which could help me. Conductance is increased with the length of wire (strip) and decreased with the width.

Thanks for your help. :smile:

I think you're looking for this:
[tex]\frac {G_1}{G_2} = \frac {L_2}{L_1} \frac {W_1}{W_2}[/tex]
You have the relationships backward. Conductance will decrease with increasing length and increase with increasing length, assuming constant temperature.
 
Thankyou. I was thinking of Resistance then which is the other way round.
