I think I got it. Since at the beginning the inductor fights the change in current, back EMF is induced in the inductance. But this means that current starts to increase according to Faraday's law: EMF=-L⋅di/dt. So current starts to increase until the stationary state is reached where current no...
Thanks for the reply, but unfortunately that doesn't answer my question. If I consider the ideal inductor, the self concatenated flux of the magnetic field is givel by: φ=L⋅i , where L is self inductance and its only a geometrical coefficient while i is the current flowing through the inductor...
Hi, I can't figure out what is the physical reason behind the fact that, in DC RL circuit, for example, the series one, the current rises from zero (supposing state zero response), to its maximum value given by ohm's law. I've understood it mathematically but I can't physically explain why...
Hi, I am a undergraduate student of engineering and I love physics. But for some topics it is very hard to understand. I have accidentally discvered this site because I was searching a doubt that I had in stationary electromagnetism topic. Hopefully, here I can make my understanding clear and...
