Combining Ohm’s Law, the continuity equation, and Gauss’ Law yields an equation describing a form of this process in conductors. For 10 points each:
[10h] Good conductors can undergo what process in which any electric field established inside them decays exponentially in time? The amount of energy dissipated by another process with this name is quantified by the loss tangent.
ANSWER: charge relaxation [accept dielectric relaxation; accept, but DO NOT REVEAL, Debye relaxation]
[10e] The loss tangent describes a form of relaxation named for this physicist that occurs in dielectrics. This Dutch-American physicist names the screening length of plasmas.
ANSWER: Peter Debye [or Peter Joseph William Debye; or Petrus Josephus Wilhelmus Debije; accept Debye length]
[10m] The time constant of magnetic relaxation is linearly proportional to this quantity, which equals the square root of “2 over mu omega sigma” at low frequency. This quantity is the depth at which current density is one over e times its value at a wire’s surface.
ANSWER: skin depth [prompt on delta]
