Best Answer

A MOSFET (metal oxide semiconductor field effect transistor) can be used INSTEAD of a BJT (bypolar junction transistor, so transistor is redundant in your question), if the circuit in question is modified to allow it and the MOSFET is chosen appropriately. BJT's will usually have a higher intrinsic gain, but have lower input resistance. Also a BJT in general will work better at higher frequencies than a MOSFET (unless you choose a high frequency MOSFET) due to the capacitive nature of MOSFETs.

How is a transistor used as a switch?

A transistor (bipolar junction transistor BJT) will only conduct in ONE DIRECTION. And the voltage drop is not Ohmic - it is *NOT* strictly related to current flow. If you're referring to a Field-Effect Transitor (JFET, IGFET, MOSFET, etc), then the device may be able to be used in a bidirectional circuit. But the question stated "transistor", which is understood to be a BJT.

What is the difference between power transistor and power mosfet?

A BJT is one type of transistor and POWER TRANSISTOR can be BJT or MOSFET or some other phenomena.POWER TRANSISTOR are usually those who are used at high current ratings e.g at POWER AMPLIFIER where large transistors are used at final stage to gain output.


Why you prefer mosfet switch?

actually I prefer a bjt


What are electrodes called in a MOSFET transistor?

The terminals on a MOSFET are called the "Source", "Drain", and "Gate". Just as with a bipolar junction transistor (BJT) the direction of current flow will be based on the doping configuration of the semiconductor. In a MOSFET, the doping configuration can be either n-channel or p-channel, but with MOSFETS, they also come in a "normally on" or "normally off" configuration, which is specified by being either "depletion mode" or "enhancement mode", respectively.


What is the difference between jfet and mosfet?

1-BJT is bipolar while JFET is unipolar. 2-BJT has low input impedence while JFET has high input impedence. 3-JFET has low power discipation as compared to BJT. 4-JFET has low noise as compared to BJT. 5-BJT is current controlled while JFET is voltage controlled. 6-JFET is mostly used in digital circuits.


Why mosfet is called mosfet?

What are the three element of a transistor?

For a BJT transistor the three basic elements are collector, base and emitter. For a FET transistor are drain, gate and source which are analogous for the BJT parts mentioned before.
