Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere. 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 ...

WebAnother example illustrating the use of Lenz’s law is shown in Figure 13.8. When the switch is opened, the decrease in current through the solenoid causes a decrease in magnetic flux through its coils, which induces an emf in the solenoid. This emf must oppose the change (the termination of the current) causing it. WebLenz’s law, in electromagnetism, statement that an induced electric current flows in a direction such that the current opposes the change that …

WebThe induced emf in a coil is equal to the rate of change of flux linkage. The flux linkage is the product of the number of turns in the coil and the flux associated with the coil. The formula of Faraday’s law is given below: ε = − N Δ ϕ Δ t. Where ε is the electromotive force, Φ is the magnetic flux, and N is the number of turns.
