 The Ohm ($\Omega$) is the unit of resistance and is a measure of a component's opposition to the flow of current ($A$). 
 
 In SI units, an ohm is defined as:
-$ \Omega 
+$$ \Omega = kg \cdot m^2 \cdot s^{-3} \cdot A^{-2} $$
+
+For non-linear devices, the differential definition of resistance is:
+$$ r = \frac{d V}{d I} $$
