      In a time-varying electrical conduction/electrostatic analysis, there is a quantity called the displacement current density, which is the derivative of the electrostatic flux density with respect to time. The source current, JS, includes both current density by electrical conduction and this displacement current density. The conduction current density, JC, does not include the displacement current density. (Ref: Theory Manual Eq 5-142.)
