In "An Introduction to Electrodynamics", Griffiths gives the following equation for the dipole moment: [itex]p=\int r' \rho(r') d\tau'[/itex]. My question is, in general, what volume am I integrating over? It seems a bit arbitrary to me. I assume I'm integrating over whatever volume is enclosing the charge density [itex] \rho(r') [/itex]?(adsbygoogle = window.adsbygoogle || []).push({});
