However, " S 1 " is pierced by conduction current, while " S 2 " is pierced by displacement current.
2.
Unlike a standard conduction current of moving electrons, displacement current is a measure of the changing electric field in the air, generated by the shifting voltages on the skin surface.
3.
In particular, he worked on hot-electron effects in short-gate length field effect transistors ( FETs ), where he showed that the high energy electrons in transistor substrates contributed significantly to the conduction current.
4.
A current, say " I ", passes outward through the left surface " L " of the cylinder, but no conduction current ( no transport of real charges ) crosses the right surface " R ".
5.
(integral form ), where is the magnetic field ( also called " auxiliary magnetic field ", " magnetic field intensity ", or just " magnetic field " ), is the electric displacement field, and is the enclosed conduction current or free current density.
6.
Also, any surface bounded by the same loop but passing between the capacitor's plates has no charge transport flowing through it, but the " ? 0 " "'E "'/ " t " term provides a second source for the magnetic field besides charge conduction current.
7.
Compared to the MOSFET, the operating frequency of the IGBT is relatively low ( usually not higher than 50 kHz ), mainly because of a problem during turn-off known as " current-tail " : The slow decay of the conduction current during turn-off results from a slow recombination of a large number of carriers that flood the thick'drift'region of the IGBT during conduction.
