Is resistance an intensive quantity or an extensive one? And why? Let me present 2 scenarios.
Resistance of a wire: The resistance of a wire depends on area and length. This implies it depends on the "quantity" of the wire taken. Does this mean it is extensive?
Resistance of a cell: As we know, resistance of a cell is $R = \dot G/\sigma$, where $\dot G$ is the cell constant and the property of the cell, and $\sigma$ is the conductivity. Now, this won't depend on the amount of electrolyte taken in the cell. Does this imply resistance is an intensive quantity?
So, my final question is, whether the resistance is an intensive or an extensive quantity and why?
