1. The problem statement, all variables and given/known data Consider a parallel plate air filled capacitor with plate area 10cm2 seperated by a distance 2mm.The potential difference across the plate varies as V=360 sin(2π 106t) volts, where t is in seconds.Neglecting the fringe effects calculate the displacement current flowing through the capacitor. 3. The attempt at a solution [tex] E=(V/d)=((360)/(2∗10⁻³))sin(2π∗10⁶t)=180∗10³sin(2π∗10⁶t)[/tex] [tex]Displacement current = ε₀(dE/dt)=10.01cos(2π∗10⁶t)[/tex] This is wrong somewhere and I donno why the area is given. Also i have trouble in understanding what this displacement current means. Is this purely theoretical current or do this actually exist?
