Where Did My Volts Go?

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.

* I gotta find those old extension cords...

Hi Mike,
I don't know what you were talking about when you said you weren't that good at video. I think you made a very impressive Science Guy. Excellent experiment and demonstration.

jw0752 You are very kind. Making the video reminded me of how much I miss teaching electrical things in person - and of how much stuff I usually explain by drawing it on a white board on the fly.

I tried to take real-time take 2 measurements and write them down, change a power supply's settings and draw a graph on paper in my last video - while speaking a foreign language. With an iPad in my left hand filming the whole thing. There must be better ways...
