In the absence of a time varying magnetic field, this quantity is conservative. For 10 points each:
[10m] Name this quantity that when multiplied by distance gives the potential difference between two plates. The flux of this quantity is proportional to enclosed charge in one version of Gauss’ law.
ANSWER: electric field [or E-field; prompt on E]
[10h] The electric field is conservative if applying this operation yields the zero vector. The right-hand rule helps determine the direction of the vector output by this differential operator.
ANSWER: curl [or del cross or rotor; prompt on cross product or vector product]
[10e] If the electric field is conservative, it is the negative gradient of a quantity described by this word. This word also describes a kind of energy contrasted with kinetic energy.
ANSWER: potential [accept potential energy; accept electric potential; accept electric field potential]
