Capacitor Wrap-Up

Concept Review: RC Circuits

A voltage source (battery) will provide an energy of Q*emf to move the amount of charge Q to fully charge a capacitor to a final voltage of value emf. The energy stored in the capacitor is only Q*emf / 2 however. Where does the other half of the energy go? It's dissipated by the resistance in the charging circuit! See details.
