A parallel plate capacitor is composed of two lossy media with relative dielectric constant &ri 12 and 82 3.5, and thickness di 1.5mm and d 3.5mm. Lossy nature manifests itself through a steady-state leakage current with the normal component Jn flowing across the interface between the two dielectric media which have electrical conductivity o1 2x 10-3 and a2 = 5 x 104 S/m, respectively. The two media have dielectric strength EMaxt = 60 MV/m and EMax2 25 MV/m respectively, where...

A negatively charged oil drop whose mass is 10-15 kg and
whose charge is -6.4 10-19 Coulombs remains stationary under the
influence of the Earth’s gravitational field and a uniform external
electric field made by two oppositely-charged parallel plates (see
diagram below). Ignore the influence of Earth’s electric field on
the oil drop.
Determine the magnitude and direction of the net
electric field created by the plates (not the electric field of the
oil drop !). Explain completely how you...

A low-loss dielectric is one with a small loss tangent, that is, (o/we) <1. We can reduce (6.52) for this special case by applying a binomial series expansion to the value within the 6.3.1 Low-Loss Dielectrics interior square root portion of the equations. The expansion is n(n-1);- + (1 + x)" = 1 + nx + 2! and for x< 1 this can be approximated as (1 + x)" = 1+ nx So we have + 1+ (6.53) 08 Inserting...
