How a MOSFET transistor works

[directcurrent10]

the transistor that your using is called mosfet transistor or metal oxide semiconductor field effect transistor...if your using an npn transistor the circuit will work if you touch the base of an npn transistor so that the current will flow then untouch it the current will not flow,,but in this case he is using a mosfet transistor so when you touch the gate(base) the current will flow and it remains on even if when your not touching the gate

[Pujc]

Any tipe of mosfet can I testing so?

How can I finding out with testing that its a N -chanel, or a P-chanel Fet ?

hi

how are you ? hope fine i like your video can you tell me sir what kind of transistor are you using ? the number??

@wearebestofworld The transistor is IRFP240 MOSFET, at 27 sec. it is shown a picture of it.

so how it works ?

@Inchique1 As shown in the video :D

For more info on the transistor itself please see other videos. Thanks.
