The charge on a parallel plate capacitor varies as q = q0 cos 2πvt. The plates are very large and close together. Neglecting the edge effects, find the displacement current through the capacitor?
Given : q=q0cos2vt To find : Id=? Formula : Id=dtdq Sol : From formula, The displacement current through the capacitor Id=dtdq=dtd(q0cos2vt)=−q0sin2vt×2v ∴Id=−q02vsin2vt
