I had a feeling someone would bring up Ohm’s law, and that’s why I said “in practice” and not “in theory”, because you are correct, in theory a shorter cable means less resistance means faster charging.
In practice, a 1m usb cable has less than 1 ohm resistance; I would imagine the difference in charge time between a 1cm cable and a 2m cable would be measured in seconds.
Also yeah, MagSafe is relatively inefficient for charging, but it is one of the most efficient methods of wireless charging, if not the most efficient (because alignment magnets).
A longer cable wouldn’t change much at all in this equation. You can test this yourself with a usb c extension cable (assuming it supports the necessary PD standards).

Shorter cable means shorter path for electrons to travel therefore faster charging, smart 😉😂
It would be funny if it actually worked like this in practice

Where is your mother entering in her credit card details?
Adding the card to wallet? Saving the card details to safari auto fill? PayPal? Just using the card on an online store?

I completely agree with this opinion.
My month old M2 MBA’s usb c ports feel mushier than the lightning ports on my 2016 iPhone SE or my 2016 iPad Pro.
I want usb c everywhere so it’s easier to connect everything together, charge anything anywhere, all that good stuff.. but I would hate for my phone’s charging port to be mushier.

That’s beautiful to see.
While I personally prefer lightning to usb c, if iPhones get a usb c port, I would love to be able to plug hard drives and accessories directly into the phone.

Sure, but I didn’t say electricity flows through wires, I said it was a shorter path for electrons to travel.
Also I was joking, this is obviously not how electricity works, otherwise you totally would be able to charge faster this way.
I like that video a lot, but that guy primarily talks about electromagnetism and alternating current; neither of those are a factor in a lightning cable, or in his car battery/light bulb experiment. Those are both using direct current.
