Describe emf and pd with a suitable example
WebUsing energy transformations, describe the electromotive force (e.m.f.) of a battery and the potential difference (p.d.) across a resistor. e.m.f. : p.d. : Medium Solution Verified by … WebMay 6, 2015 · where Φ is the flux threading the disk and E is the EMF drop around the loop. This is called Faraday's law. So, for each imaginary disk inside your coil we get some EMF as the flux through that disk changes in time. Now think about the bar magnet's descent. Suppose we drop it starting way above the entrance to the coil.
