Nice, short explanation. I was surprised by the skin effect becoming so significant at such low frequencies, like the 60kHz example, and also wasn't aware of the reason for braded grounding straps.
Just one minute in, with that one graphic of the H field loops causing eddy currents inside the wire, and I understood intuitively how AC causes the skin effect. Great video! Many thanks!
Does the 20kHz typically found in PWM circuits for DC motor control result in any skin effect? My specific application is for a 12V, 30A brushed motor with a Kv of 140. Should I take skin effect into account when selecting the correct gauge of wire?
That's a really good question I'd love to know the answer to. I imagine pwm would have to produce skin effect as its frequency is increased enough. However, pwm doesn't necessarily require negative voltage so idk.
Wow insanely informative. So is this why communication wires are often so small? Or is that just because the amount of power running through doesn't need to be much?

The video is bloody amazing
That's a cool solution to skin effect for HF cables.
Please use a lapel microphone.
Very good overview of the skin effect. Shame about the fan noise
Liked this.
Your audio is horrible. Sounds like your microphone is 20 feet across the room.

please speak slowly. so that viewer can understand better. this is not a race to speak fast.
