hi
my elementary doubt is how inductor oppose changes in current
eg
if i connect 10v battery to an inductor.
assume inductor has no energy stored
voltage across inductor is 0v,
at t= 0 --
current thru the inductor is 0
resistance is 1ohm.
if i connect 10v battery to inductor at t=0
i = 10V/1 =10A.
IS this inrush current??
exact definition of inrush current ??
wen a sudden 0 to 10A current flow thru an inductor, by electromagnetisim , a change in magnetic field around the inductor will be created,
is this change in magnetic field. cauce force on the inductor ?
(when a current carying conductor in a magnetic field experience force )
is this force is the reason for the inductor oppose to changes current.
or by faradys law
changes in magnetic field produce an emf induced in the conductor by LENZs Law the direction of induced emf is which oppose the cauce.
that means induced emf produce a current ,this current will produce another magnetic field ,
this magnetic field should oppose the main magnetic field, so the current direction is opposite to the applied current
if applied current is ( 0 to 5A) , AT SAME TIME , is inductor oppose a current ( 0 to -5A),??
IF THE SELF INDUCED EMF IS 180 DEG PHASE SHIFT OR equal and opposite,
induced emf is -10V,
then applied voltage and induced emf cancel each other,
no current, no magnetic field,
really i try to visualize this small inductor , its principle, by eqn and mathematically its ok.
pls help me ,whats the true working principle from deep basic on electromagnetisim..
also point out my misconcept.
regards
