If [itex]\phi[/itex] is a scalar function like the electrical potential, then its gradient, written as [itex]\nabla\phi[/itex], is the vector [itex]\frac{\partial \phi}{\partial x}\hat{x}+\frac{\partial \phi}{\partial y}\hat{y}+\frac{\partial \phi}{\partial z}\hat{z...
What is electric potential? What would you expect an electric field to look like inside a hollow conductor? What's the significance of the value of C^2/g where c is the speed of light and g is acceleration due to gravity? What problem solving advantages do scalar and vector potential fun...
Thus, the Einstein–Maxwell-dilaton theory is an interesting and sim- ple theoretical arena for exploring modified gravities which involve scalar and vector fields, while black holes are very important objects in terms of strong gravity. In this paper, we approach the case of a static particle ...
To create HsrF in the plastic tank, I have implemented an abelian local symmetry calculation by using MATLAB software, considering the gauge field symmetry and the Goldstone scalar with respect to the longitudinal mode of the vector [7, 15]. Thus, for each spontaneously broken particle Τα of...
Direction of electric field vector on the surface of charged conductor Consider a negatively charged spherical conductor. On the surface of it, what is the direction of its electric field? Well, the definition of the direction of an electric field is the direction a positive test charge would ...
Here the vector r for our 2D circuit is defined as r = na1 + ma2 where (n, m) are integers varying between −(N − 1) to N and δ represents the Kronecker delta rather than the Dirac delta function of the continuum electrostatic model, due to the discrete ...
the flux model has been implemented in this paper by utilizing monitored rotor speed and stator voltages along with currents. It is obtained from basic stationary reference frames (α, β) associated with the stator. The rotor flux space vector is achieved and are resolved into the α and β...

The field-strength tensor for the electric field is given by [Math Processing Error]Fμν=∂μAν−∂νAμ. (6) We consider the static electric field only, then the vector potential is given by [Math Processing Error]Aμ=[A0(r),0,0,0]. (7) Then the nonvanishing components...
