Instructions and help about MECHANICAL OR ELECTRICALLY OPERATED Travelers

This video was sponsored by Caséta by Lutron. Imagine you have a giant circuit consisting of a battery, a switch, a light bulb, and two wires which are each 300,000 kilometers long. That is the distance light travels in one second. So, they would reach out half way to the moon and then come back to be connected to the light bulb, which is one meter away. Now, the question is, after I close this switch, how long would it take for the bulb to light up. Is it half a second, one second, two seconds, 1/c seconds, or none of the above. You have to make some simplifying assumptions about this circuit, like the wires have to have no resistance, otherwise this wouldn't work and the light bulb has to turn on immediately when current passes through it. But I want you to commit to an answer and put it down in the comments so you can't say, oh yeah I knew that was the answer, when I tell you the answer later on. This question actually relates to how electrical energy get from a power plant to your
