A time-varying voltage source v(t) 10cos(ot) is applied across a parallel-plate capacitor. The plate separation is 2 cm and the plate area is sufficiently large that fringing may be neglected. The interior polystyrene dielectric has a relative permittivity of 2.56 and a conductivity of 3.7 x 10 S/m. lacement current densities within the polystyrene, a) at f 1 MHz and b) at f 100 MHz.
