Question
The Lorenz gauge condition can be written as an equation featuring the term "one over c-squared times this operation applied to the scalar potential." The E-field equals minus-del-phi minus this operation applied to the vector potential. This operation applied to charge density equals the negative divergence of current density by the continuity equation. This operation applied to the displacement field gives displacement current. This operation gives the negative curl of the (*) E-field when applied to the B-field. This operation is applied to magnetic flux to calculate the e·m·f with Faraday's law. This operation applied to charge equals current. For 10 points, name this calculus operation written "d-d-t." ■END■
ANSWER: partial time derivative [or partial derivative with respect to time; prompt on partial derivative; prompt on d-d-t before the end; prompt on answers describing division by time, like x over time, by asking "what calculus operation is equivalent to dividing by time at an instant?"]
