I think the confusion is that Veratisium's original video made it seem like this was the only/main way electricity travels, whereas in reality, there's two separate ways: One of them take's 1/c and the other takes c/2. Also, what most people think of the light bulb going on in the real world would be the c/2 one, not the 1/c one.

What is c/2?

1/c was because the distance between the lightbulb and the battery was 1 meter. m / m/s = s

With c as the numerator, I don't even know what the units of that 2 would be? m/s²?

Err, sorry, I mean't 0.5s, which is option A in Veratisium's video, and the time it actually takes for the current to go through the wire.
