Induced charge density on dielectric
Webε is the Fourier transform of the dielectric constant, k is the wave vector of the field, ρ ind ( k) is the Fourier transform of induced charge density, and φ ( k) is the Fourier transform of the total potential. The physical consequences of one part of this formula are easy to see. Since one part of ε is proportional to 1/k 2, ε is ... WebSince the battery is disconnected before the dielectric is inserted, the plate charge is unaffected by the dielectric and remains at 0.8 nC. With the dielectric, the potential difference becomes V = 1 κ V 0 = 1 2.1 40.0 V = 19.0 V. The stored energy without the dielectric is U 0 = 1 2 C 0 V 0 2 = 1 2 ( 20.0 pF) ( 40.0 V) 2 = 16.0 nJ.
