有題有關電磁學的問題一直想不透
不曉得如何下手想請問版上的大大
題目如下
You have a parallel plate capacitor with area S.
The capacitior is connected to a time-varying voltage source V(t),
providing a time-varying current with amplitude of Io.
Asuume you can neglect edge effects.
(a) Find the amplitude of the displacement current density in each dielectric
(b) Find the electric field intensity in each dielectric.
(c) Find the voltage amplitude across the capacitor.

根據題目的圖
那個平行板電容應該是中間分了兩層不同的介電質
(第一次發文不曉得可不可以在這裡問)
