## Main Question or Discussion Point

Background: an ordinary wire supports an external radial electric field proportional to voltage, and an internal axial field equal to current times resistance per unit length. The present question is

In a discussion of this, the second question led to the first one. A Poynting vector interpretation of an external tangential component of the E field would indicate power flowing from the conductor into space, even for zero frequency (DC). This seems implausible, hence the question.

**whether the internal axial field has an external counterpart**. The original question that generated this inquiry was:**How does the electric field (therefore the electric force) in a wire remain parallel to the wire even if it is randomly curved (current still flows)?**In a discussion of this, the second question led to the first one.
