Charge Density of a Voltage Pulse

  • #1
If I make a single, short (GHZ) negative voltage pulse propagate down a long, single wire which forms a closed circuit, will there be a corresponding negative charge density in the conductor (shown as bunched-up green electrons) which propagates with the pulse?

Not in a relevant amount, but in principle, yes.

Thank you for the reply.

I was curious if the pulse would just propagate through the conductor like radio waves though space - without the need for or effect on electrons, but I just couldn't see there being this potential at some point in a conductor without an effect on the density of electrons in that region, however small that region or minuscule that density might be.

It's just a curiosity, but I didn't know!

Thanks again :)
