This gate permits electrons to flow through or blocks their passage by creating or eliminating a channel between the source and drain.

Why the name is FET?

FET stands for Field Effect Transistor. The name FET comes because the gate current of a field effect transistor is zero and current present in the source conductor is due to an electric field produced by the substrate material placed between the gate and the source.

Why jfet called as fet?

FET is a field effect transistor, abbreviated to FET. There are two basic types of FET: a junction FET abbreviated to JFET and an insulated gate FET , abbreviated to IGFET. The most common type of IGFET is a metal-oxide silicon FET, Known as a MOSFET. Modern microprocessors may contain tens of millions of MOSFETs.

Can you use a fet as a capictor?

No. Not for any practical capacitor value. There is an inherent capacitance between the gate and the drain/source channel, but it's only a few picofarads.

Why you use FET?

FET's improve the switching frequency from KHZ to MHZ.. FET can be used as temperature sensor.. and mosfet is used as a switch..


Why fet operated in reverse bias?

you want to keep the channel electrically isolated from the gate (jfet) or substrate (mosfet) so that it operates as a fet, don't you? if it was forward biased it would just be a diode with no field effect.
