What is RDS(on) AKA On-Resistance?

[@jamiereynolds4398]

Thanks for making this video, really helped solidify my understanding of MOSFET's prior to my exam! :D

Jamie Reynolds Awesome :)

Hi! And what about an ordinary bipolar transistor? Can we use this same concept?

[@BladeScraper]

short and simple, thanks for the explanation :)

Why is the second measurement technique inaccurate? Seems like a logical method

[@HeilmanHackatronics]

The current the ohm meter is pushing through the transistor is very little. so unless you are driving a low power device such as an LED, The resistance measured will be lower than the intended circuit. The higher the resistance will cause more power to be dropped across the transistor. Heat sink needed.. thermal effects to other components... Anyway thanks for the view

Now I can determine whether my IRFB4110 are fake and will eventually burn down my BLDC escooter controller. This video might save lives :)

i appreciated it. )

[@IceCubedSun]

what does on resistance mean?

[@jonsanford0]

The 'trick' is too much like putting ohmmeter on a live circuit
Mo bad habits

[@HeilmanHackatronics]

I measured no voltage prior to the ohm meter
