um, not a physicist, but the top answer seems a misconception. Electricity is part of the electro-magentic spectrum, so never mind the speed of sound – it travels at the speed of light.
So it doesn’t make a sonic boom for the same reason photons don’t make sonic booms. Also, veritasium did a video that breaks down *how* exactly electricity travels “down” a wire (it doesn’t – it’s complicated).
