Hi,
An inductor connected to a DC power source via a switch. Now consider you open the switch, What will happen to the current? I do know that we will have a spark due to current but I am not sure about the direction of the current while opening the SW?
Before now, I thought that when we make the SW opened, then the current direction will be reversed (I.e the inductor polarity will be reversed) but when I read about something called kick current or so I noticed that after opening the Sw the current tends to continues its direction (not reversed), right?
If so please tell me why when we connect a reversed biased diode parallel to the the inductors (specially relays) then the diode will be in direct biased when we open the SW????
Is there any reversed current inside the inductor when functioning or while opening?
Thanks.
