How fast does electricity interruption travel?

We did an experiment in under graduate school. A signal traveled through fifty feet of coaxial cable at 0.8 C.

But I still can’t credit Ali’s tall tale.

I’m starting to think he also maybe couldn’t sting like a bee either. Humans have no venom glands, nor any way to inject it in a victim.

This. I am finding it difficult to believe than anybody would think the statement was anything but hyperbole. Ali could teach a master class in hyperbole.

The propogaton velocity of the E and M fields around the wires is always less than c, and depends on a number of variables. For most pairs of wires, the velocity is somewhere between 0.4c and 0.8c:

In the computer networking class I took in college, we always used 0.67c as our approximation for propagation delay in our formulas.
