WebApr 6, 2024 · For a varying magnetic field the magnetic flux is dΦB through an infinitesimal area dA: dΦB = B⋅dA. The surface integral gives the total magnetic flux through the surface. ΦB = ∫∫A B⋅dA. According to Faraday’s law formula, in a coil of wire with N turns, the emf induced formula in a closed circuit is given by. EMF (ε) = - N. WebThe answer is that the source of the work is an electric field →E E → that is induced in the wires. The work done by →E E → in moving a unit charge completely around a circuit is … WebR=P l/a. Where p (rho) is the resistivity of the material. l is the length. A is the area of cross section. So for 0 resistance the resistivity (p) should be 0 which is not possible because all materials have electrons in them ( that is obvious for flow of current ) and the repulsion of electrons cause resistance and all materials have positive ... highest grade of school completed oregon
