Interesting. Even though the current through the inductor goes in the same direction immediately after turning the battery off, the measured voltage drop across the inductor flips from steady state zero to negative. The magnetic field shifts from becoming the consequence of electron flow to the cause, as the magnetic field collapses. I suppose that should be obvious....
When you first close the switch the voltage to the left of the resistor should jump instantly to 25 volts. It's a step just like it jumps instantly to zero when you open the switch. I also believe the term exponential is confusing. Is logarithmic correct, I'm not sure either. Maybe negative exponential or inverse exponential. There is an "e" in the differential equation. I'm 61 and that is way to far back for me.
very difficult to see the polarities of voltage and directions of the current when inductor is charging/discharging. just that its increasing/decreasing. both terminals are labeled by a + polarity what does that mean? red color should signify positive voltage polarity, but im not sure that is what its doing here.
That's not called an exponential increase dude. It's like K-exp(-at)=> K as t -> inf. By looking at the graphes only, you might even say there's logarithmic increase
This might have just saved me right before my exam - excellent job explaining!
Great to hear and best of luck for the exam!
This is beautiful , this is how science was meant to be taught.
So nice of you to leave such a nice comment.
Very clear appreciate the help studying for my Physics 2 final
Thank you very much for watching and commenting. Hope the final went well.
Thank you for your effort. Very helpful
You are very welcome.

I got clear cut understanding. Thank you
Great!
at 4:27 - 4:32 the voltage across the inductor is showing +25V, shouldn't it be opposite, -25V? Thanks
OK yes, but the magnitude of the potential difference is 25. sorry for my mistake.
@@stepbystepsciencelol sry, I just trying to learn electronics on my own, so confusing
Thank you so much!
You're welcome!
you're perfect! Thx a lot

thank you sir
Most welcome
Which simulator you are using?
The simulations are from PhET simulations, I mention them at the beginning of the video.
Sweet
You are very welcome again!
Que rasca la explicaciòn , se necesitan los elementos reales y las ecuaciones... NO sirve asì

OK, but what is your opinion about how I explained the overall concept of charging and discharging the inductor?
I liked it. Good job.
Thank you.
