# RLC changes negatively when is measured in the inverse sense?

If $V_{BA} = P_B - P_A$ (where V is the voltage and P the potential) so, $V_{AB} = - V_{BA}$. The same ideia for the current: $i_{BA} = - i_{AB}$, so this ideia of sense is true too for resistor, inductor and capacitor? The resistance, inductance and capacitance of an arbitrary sense is the same in the contrary sense or is negatively equal in the contrary sense?

The resistance is the same in either direction. R=V/I, if you have a negative current then you will also have a negative voltage so that R is the same.

Similarly for other passive elements.
