Hello everyone
I was hoping you could help me with a concept that is mixing me up a bit.
it's a simple inductor circuit.. first current passes through the circuit till it's charged fully storing energy inside its magnetic field.... However when the switch is opened later.. the reaction of the inductor doesn't make sense to me....
We know that inductors resist change in the current through them... before the switch was opened current was passing through the inductor entering from the upper side... therefore when the switch is opened the inductor induces a voltage which will drive a current that should enter through the upper side as well right....
However looking at the polarity of the inductor when the switch is open.. the negative terminal is the upper side of the inductor and vice versa.... Now why would this drive a current entering through the upper side of the inductor... because there is a physical connection between both terminals... and we know that current goes from positive to negative... why doesn't the current just go upwards directly to the negative terminal (that is assuming of course that the inductor is connected to smth like a resistor which closes the circuit... Why would the current take the long route in a sense? In a battery it's because the only way to reach the negative terminal from the positive terminal is the load... but in an inductor's case it's a different..
Thank you
I hope my question is understood..
