where [D.sub.2n], [D.sub.1n] are the normal components of the electric displacement vector: [D.sub.2n] = [[epsilon].sub.0][[epsilon].sub.2] [E.sub.2n], [D.sub.1n] = [[epsilon].sub.0][[epsilon].sub.1] [E.sub.1n] [epsilon].sub.0] = 8.85 [10.sup.-12] F/m is the electric constant; [[epsilon].sub.1], [[epsilon].sub.2] are the dielectric permeabilities of dielectrics, a is the surface density of electric charges; [E.sub.1n], [E.sub.2n] are the normal, [E.sub.1t], [E.sub.2t] are the tangential components of the electric field strength vector of the first and the second dielectrics, respectively.
Assuming constant inductance L, and adopting [C.sub.e] as an electric constant of the exciter, the sum of voltage drops in the coils circuit was described by the Eq.
Pairing a 97bhp 1.8-litre petrol engine and a 53kW electric motor delivering a further 71bhp with an electric constant variable transmission the system just works really well - offering smooth, relaxed and quiet progress.
Pairing a 97bhp, 1.8-litre petrol engine and a 53kW electric motor delivering a further 71bhp with an electric constant variable transmission the system just works really well.
Millikan's calculation of the electron's charge was within an outstanding one percent of the presently accepted value of the electric constant, falling short only because the experimentally-gained value used for the air viscosity was slightly low.

where the electric constant becomes linear density of the vortical tube, and the reciprocal of the magnetic constant is the centrifugal force produced by rotation of the vortical tube element with [m.sub.e] mass with the velocity of light c along [r.sub.e] radius.
