Tell them when they try to sell you expensive cables. Very nonintuitive but true.
Derek Muller holds a Ph.D. in physics.Yup mostly correct but his 1/C seconds answer is not really right. You would get instant current due to capacitance, probably almost none and the bulb would not turn on but some current would flow. That would take 1 second to actually turn on.

1/c per potential second at all distances - the current doesn't reach 100% that fast (according the the video).
Yes. But unfortunately this thread double posted so please continue it here.
Speaker wires don't carry any energy (power).

The 1/c answer certainly feels wrong, that’s for sure.
Could a dude with a wire cutter at the bend 1/2 light second away not send information instantaneously by cutting the wire?
That is, what happens if the wire is cut just before the switch is flipped? The bulb must act exactly as if the wire was not cut for at least 0.5 s, or else we have just transfered information faster than the speed of light.
The energy is being transmitted by photons, which is where the 1/c comes from. If you want an alternate visualisation of what's happening you could take a look at this:But its not the field that exists between the source and the light bulp that delivers the energy to the bulp. Its the field around the wires that follows the wires. I dont think that 1/c assumption is correct. Iam not a physicist so if iam wrong i dont loose my reputation . So the bulp could see the field of the source in 1/c but it would not power it. We would need only tiny wires if this would be different. No current needet would be cool.

Why do people need to comment on things that they have no idea what-so-ever?
My First tout was is he considering transmission line impedance and what is the impedance.
in this case the cable don’t even have to be connected at the ends for light to become on instantly.
You can also consider it a 2 dipole antennas close together
