To introduce capacitance to connect charge and potential, and to describe its general properties, both for single capacitors and in combination. To introduce electric flux and flux density, D ,and relate them to the charges setting up a field. From this to formulate Gauss' law. To connect D...
Electric field can also be expressed in terms of electric potential (V) and distance (L): E=VL Here, V is measured in volts (V) and L in meters (m). Thus, substituting this into the electric flux formula gives: Φ=E⋅A=(VL)⋅A The units of electric potential (V) are volts...
The specific charges can have the intrinsic charge from the seed charge attached by remanent electric flux inside the effective corresponding charge body under the postulate that at the time of universe birth, there were seed charges with charge , -Ke where K>0, e>0 is the absolute electron...

Homework Statement: circuits - terms Relevant Equations: - How exactly can the electric potential be constant between two points in a wire; (assuming that it is electron current); if the electron is moving from a region of high electric potential to a low electric potential because of the.....
We shall apply Gauss's law to explain some dielectric phenomena resulting from electric polarization. As discussed in Gauss's Law in Chapter 1, Gauss's law simply states that the electric flux outward from a volume is equal to the total net charge enclosed inside it. We use a simple system...
As is well known, the plasticity of nearly all metal materials in electric and magnetic fields is changed to some extent, which is so-called “electro-plasticity” or “magneto-plasticity” [12]. In addition, it was found that great progress in metal properties, in terms of the improvement...
However, in this way the power drawn from each device cannot be controlled, but is passively determined by the impedance of the devices. The impedance depends on many parameters, e.g. temperature, state-of-charge, health, and point of operation. Each device might therefore be operated at an...
The energy stored, W, in the magnetic field of an inductor is given by: W=12LI2 joules. 13 (i) Induced emf in a coil of N turns, E=N(ΔΦt) volts, where ΔΦ is the change in flux, in Webers, and t is the time taken for the flux to change, in seconds. (ii) ...
So, the natural flow of electric charges and magnetic flux is associated also by increase of entropy of universe, similar to the heat, and has the same nature of waves as the electromagnetic heat radiation. Casting the Maxwell's wave equation into an energy frame of reference that replaces ...
