In every video, you said when you measure mosfet or transistor "this have this much voltage drop" while your multimeter is still in continuity mode or meter in diode mode. How it is possible when there is no power is given to motherboard. is there are any specific terms you are about to say.. I confused. please clarify if it is possible in next coming video.. thanks in advanced.
I wish to know the same too.
THERE IS POWER THROUGH THE MULTIMETER, PLENTY OF VIDS , DO A SEARCH ON THAT SPECIFICALLY
When a meter is in diode mode, it attempts to pass DC voltage between the leads. Diodes will only pass voltage in 1 direction and that junction usually shows a 0.6V difference which is what the meter will show. Some will provide a audio "beep" if the 0.6V value is attained.

I could respond this for Alex but looks like you wanna hear it from him!
Multimeter in diode mode measure voltage drop, remember that multimeter becomes a (mini power suply) when measuring in diode mode and somes, in continuity mode so, if the multimeter suply 2.5 volts, the screen only shows the many volts the (measured part takes from those 2.5 volts) wich is mostly, 0.450 (diode reference voltage) as transistor are made with diodes and diodes are ........DIODES!!
Thanks for reply to you all.
