This chapter focuses on the behavior of the electric field, current density, and the potential in conducting and nonconducting media. In the absence of the field E 0 , the net charge on the confined body is zero. The field in the absence of the inhomogeneity, E 0 , is usually called ...
In 1963 Ridley postulated that under certain bias conditions circuit elements exhibiting a current- or voltage-controlled negative differential resistance will separate into coexisting domains with different current densities or electric fields, respecti
Corona power loss, electric field, and current density profiles in bundled horizontal and vertical bipolar conductors In this paper, computation of the corona current and, hence, the corona power loss associated with bipolar high-voltage direct current (HVDC) conductors is... ZM Al-Hamouz - 《...
Related to electric flux density:magnetic flux density electric flux density n. A measure of the intensity of an electric field generated by a free electric charge, corresponding to the number of electric field lines passing through a given area. Also calledelectric displacement. ...
where E is the electric field in V/m, ρ is the charge density and ∈0 is the permittivity of air. The electric potential (in volts), defined as the work done in bringing a unit of positive charge from infinity to that point, can be derived from Maxwell’s equation and is related ...
This point can also be evidenced from the work of B. Su et al. on seed growing, where the nsPEFs treatment with low intensity could elevate the germination rate of Haloxylon ammodendron seed, while high field intensity would lead to significant inhibition25. The SEM pictures of S. ...
You may not recognize Equation [3], but it is actually famous - this is Ohm's Law. You probably know from electric circuits that V=IR, which relates voltage, current and resistance. In Equation [3], the E-field is analogous to voltage, current density is analogous to current, and the...
(the inverse of resistivity) relates the Electric Field (like Voltage) to the Electric Current Density: [Equation 2] Since the conductivity is infinite, if an electric field existed within the material, the current would be infinite. This can't happen. ...
A commercially available spreadsheet program is used on a microcomputer to calculate the electric field/current density distributions induced in irregularly shaped, inhomogeneous objects by low-frequency magnetic fields. A finite-difference method is applied to an impedance grid that represents the object ...
Static magnetic field A charge q moving at velocity u is a current i = qu, and is therefore subject to a force if it moves across a magnetic field. The force is at right angles to u and to B, the magnetic flux density, and in the simple case of Figure 2.30b we have f=quB=ma...
