Where Did My Volts Go?

kmikemoo

14 Sep 2020

What's not to love about seeing science in action?  We can't always see the actual event but we can see the results.  In troubleshooting, I call them symptoms, because the event we can measure or observe isn't the root cause.

 

I also decided to try making a video.  Wow.  It's even harder than I imagined.  Note to self... you're not that good.

 

I decided to "prove" Ohms Law through demonstrating voltage drop.  It's in the video.  Of course, things didn't go as planned - but I had a lot of fun (and frustration) so I decided to share it anyway.

    You can prove inductance by keeping the extension cords wound up on a roll .

    Oh, I have used similar ones in the past by myself. I just value my life too much to ever connect to to mains (granted, it 240V over here).

    dubbie  I see you've noticed the "Executive storage".  I'm just happy that the company president sold his other boat - because there used to be two of them. image

    Nice experiment. Just shows that when we think we are measuring the real world, many times we are not.

     

    Nice boat too.
