>>13869864if you're so buttmad why don't you prove it? Seems like it would be easy to demonstrate. Get like 30 meters of wire, put em' side by side and apply a voltage pulse, use something to measure the voltage on the other side. There's probably some RF bullshit you could do, but with a long enough wire and repeatedly applying pulses you could probably see it on an oscilloscope.
>>13870289but you get electric and magnetic fields outside the wire too and those only need to travel 1 meter. The two wires are like two giant antenna next to each other. The transient effects are weird and the bulb doesn't reach full voltage immediately.
>>13870414it travels in 1/c because the bulb is 1 meter away from the battery, it would take longer if the bulb and battery were further apart
