Thankyou. I was thinking of Resistance then which is the other way round.

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...
