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:
|
|
$$ \Omega = kg \cdot m^2 \cdot s^{-3} \cdot A^{-2} $$
|
|
|
|
For non-linear devices, the differential definition of resistance is:
|
|
$$ r = \frac{d V}{d I} $$ |
