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.
