thermal stress distribution, the fracture is presumed to be due to thermal stress and sublimation of specimens.The results obtained were as follows:(1) The relationship between the current density and length of time required for fracture is obtained by the following formula:i=At-nwhere n=0.3-...
55 problems 1PRACTICE PROBLEM Two tiny balls charged to +5.1 μC and +7.21 μC are used for an electrostatics experiment. They are joined together using a massless non-conducting rod 3.21 cm long. The +5.1 μCcharged ball is fixed in place while the other charged ball is free. The asse...
Power Formula 1– Electrical power equation:PowerP=I×V=R×I2=V2⁄R where powerPis in watts, voltageVis in volts and currentIis in amperes (DC). If there is AC, look also at the power factorPF= cosφandφ= power factor angle ...
The spin current transmission properties of narrow zigzag graphene nanoribbons (zGNRs) have been the focus of much computational research, investigating the potential application of zGNRs in spintronic devices. Doping, fuctionalization, edge modification, and external electric fields have been studied as...
We analyze the dynamic toroidal multipoles and prove that they do not have an independent physical meaning with respect to their interaction with electromagnetic waves. We analytically show how the split into electric and toroidal parts causes the appear
An analytical prediction of the total corona current was also attempted [19]. A more elegant solution is provided by Kaptzov's hypothesis that the electric field on the surface of corona electrode remains constant at a value given by Peek's formula [20,21,28–30,32,36,39,43,45–48]. ...

Here, we provide a detailed pedagogical exposition of the impedance formula in Eq. (3), which has an analytic expression thanks to the fact that the method of images can be used in implementing the circuit boundaries. Besides our method, one can also compute the complex equivalent resistance ...
The concept of an apparent grain boundary energy, which is a linear function of the square of the current density, is introduced. One needs to use the apparent grain boundary energy in analyzing the equilibrium state of a trijunction. An expression for the rate of grain rotation is proposed,...
