I am sorry to ask this elementary question but i have some doubts that were not cleared during my undergrad days. I will try to present my doubts in following points.
1 At t=0 , there is no current so no magnetic field inside inductor but there is a voltage equals in magnitude to that of source.
* Where does this voltage comes from, many people say that it is due to fact that inductor oppose to change in current but my questions is what is the phenomena which leads the inductor to develop voltage to oppose current.
** How the voltage is equal to source voltage even in the presence of intrinsic or external resistance.
*** Then what leads the current to flow just after t=0 say at t=0.00000..1 sec as source voltage and load(inductor voltages are equal).
Dear Aparna Sathya ,
Thanks for your answer but that is not my question exactly. I am asking why at t=0 ust the instant the switch is close inductor voltage is equals to source voltage mathematically it is due to the fact that we put t=0 in first order differential equation which gives us answer V(t)=V(L) but why does it happens and after t=0 why it allows the current to pass through it.
