{title=<I-V curve> of a <diode>}
{description=This image shows well how the diode is only an approximation of the ideal one way device. Notably, there is this $V_d$ non-ideal voltage drop across the device, which can be modelled as constant. It is however an exponential in fact.}

Good video:
* https://youtu.be/Fwj_d3uO5g8?t=153 how it works
* https://youtu.be/Fwj_d3uO5g8?t=514 applications:
* protection against accidental battery inversion
* <rectifiers>, notably mentions a <diode bridge>
