The charge on a parallel plate capacitor...

The charge on a parallel plate capacitor varies as q = `q_(0) cos 2 pi gamma` t. the plates are very large and close together. (area- A, separation -d) find the displacement current through the capacitor?

conduction current Ic = Displacement current ID
`I_(c ) " "= I_(d) = (dq)/(dt) = (d)/(dt) " "(q_(0) cos 2 pi gamma t )`
` = - 2 pi q_(0) gamma sin 2 pi gamma t.`
