The field picture of energy transfer in a circuit says that energy travels

  • A.as a flow of electrons along the conductors
  • B.as heat conducted along the conductors
  • C.instantaneously, with no propagation delay
  • D.in the space around the conductors, not within them

Answer: D

The Poynting vector is largest in the space between and around the conductors, and the conductors serve to guide it rather than to carry it. The circuit and field pictures agree on the total power but differ entirely on where it goes.
