The flow of water through a hose can be controlled by squeezing it to reduce the cross section and the flow of electric charge through a JFET is controlled by constricting the current-carrying channel. The current also depends on the electric field between source and drain (analogous to the difference in pressure on either end of the h… quarter midget throttle cable https://ambiasmarthome.com

WebApr 25, 2024 · 1 Answer. For any particular gate-source bias voltage, when the drain-source voltage reaches a certain value, the characteristic of drain-source voltage vs drain current becomes a near-straight horizontal line. This is the "pinched-off" current and it is near constant with changes to drain-source voltage. Picture taken from this quora page for ... WebNov 18, 2024 · When we increase the drain voltage, the channel to gate voltage difference also increases. However, this difference is more towards the drain terminal. Hence depletion layer towards drain terminal get thicker faster than that towards source terminal.

WebThe Cutoff Voltage of a JFET is the voltage that is needed at the gate-source region of the JFET in order to turn it off. At this point, the transistor enters the cutoff region . For JFETs, the cutoff voltage is referred to as V GS,off, because it is the voltage which must be applied to the gate-source terminal to turn off the transistor. Webdrain current is reduced to a point where the FET is no longer conductive, the maximum resistance is reached. The voltage at this point is referred to as the pinchoff or cutoff voltage and is symbolized by V GS = V GS(off). Thus the device functions as a voltage- controlled resistor.
