Maxwell’s Displacement Current

• The Electric Field E between the plates of the capacitor is determined by the chrg Q on the plate of area A: E = Q/(Ae0)

• What we want is a term that relates E to I without involving A. The answer: the time derivative of the electric flux!!

Therefore, if we want ID = I, we need to identify:
