JizzaDaMan said: Well if the resistance of the lamp is ΔV/ΔI at any point on the graph, then given that the relationship between the voltage and current for the lamp is non-linear, this will not be V/I which by Ohm's law is the formula for resistance. The original definition of Ohms Law was just the linear equation V=IR.
