The charge on a parallel plate capacitor varies as $q , = , q _0 , cos2\pi \nu t$. The plates are very large and close together (area = A, separation = d). The displacement current through the capacitor is then
- $3q _0 \, 2\pi \nu \, sin2\pi \nu t$
- $-q _0 \, 2\pi \nu \, sin2\pi \nu t$
- $4q _0 \, 2\pi \, sin2\pi \nu t$
- $5q _0 \, 2\pi \, sin2\pi \nu t$
