1. The problem statement, all variables and given/known data The conductance G of a device is defined to be the inverse of its resistance, G=1/R. What is the conductance of a device through which the current is 2 A when a potential difference of 60 V is applied? 2. Relevant equations R= V/I R= (resistivity)X (length)/Area 3. The attempt at a solution I first found the resistance by using the first equation, and got 30 ohms but then I get stuck...because I don't see any other formulas that that uses resistance that allows me to find the resistivity constant...and I don't have the length and area for the second equation..
