| Aug 12, 2016 at 17:28 | comment | added | Claudio Avi Chami | The current is determined by V/R for resistors, not for any component. For diodes, Ohm law is NOT relevant | |
| Aug 12, 2016 at 17:27 | comment | added | Eugene Sh. | Anyway. \$R\$ is not constant for LED. The generalized \$R\$ (you can't call it resistance anymore, probably) would be \$\frac{dV}{dI}\$. And for the IV curve of a diode it is not constant. | |
