Field effect transistor:

Primarily difference between bit and jet is that bit transistor is a current controlled device while jet is a voltage controlled device.  Is a direct function of level of if current id will be a function of the voltage applied to input circuit?

Just as n-p-n and p-n-p bjt there are n- channel and p-channel field effect transistor.

But is bipolar device thwart is a function of charge carrier's electrons and holes.  Feet ions an unpopular device either electrons or holes (p channel). Conduction for the aft in an electric field is established charged present that will control the conduction path of input, without the need for direct contact between the controlling and controlled quantities. one of the most important choristers of aft is a high input independence from 1 to 100 m bit output are more sensitive to change in input quantities while aft output are less sensitive to change the input quantities or in other  in other word feet are more temperature stable than bit. Aft are smaller than in construction then bit.

Two type of aft area there.

(!) Jet - junction effect transistor

(ii) misfit- metal oxide semiconductor field effect transistor
