8. Please verify that the displacement current Id between two parallel
of a capacitor is equal to the physical charging current I. (10%)
Please prove that Id can be written as C(dV/dt), where V is the potential
difference between the plates, and C is the capacitance. (5%)
這題中的displacement current是什麼意思...不了解
