Hi Dale,
Thanks for the replies. I found a link on that same page you sent that has another interesting statement:
For electromagnetic waves, both the electric and magnetic fields play a role in the transport of energy. This power is expressed in terms of the Poynting vector...
Hi Dale. Thank you for continuing to respond with insight. It makes sense that a battery supplies energy, but that energy must continue to propagate through the circuit. How does energy continue to propagate to a battery once the circuit has been formed? I always thought the electrons...
Thank you for responding. It would certainly clarify things for me if there were no waves in a DC circuit other than maybe a transient wave when it is first switched on or connected to a power source. The problem is, everything I've read states that the electrons themselves are not carrying...
Thank you, Zz. I will see if I can find some online articles covering solid state physics. I would love to learn more about electron group waves and electromagnetic wave propagation in copper wire DC circuits. The common explanation of how electricity works in copper wire circuits is so...
Hi all,
I still can't fully understand why electrons only drift in a copper wire DC circuit. The basic explanation I've been given is that electromagnetic waves carry the energy and move at roughly half the speed of light in copper, while individual electrons only drift along as the medium...
