Circuits I: Example with RLC Circuit (Parallel, Natural Response)

This video works through a problem involving a circuit with resistor, capacitor, and inductor in a parallel configuration. We examine the natural response of the voltage following a switching event.

I really had a bad time trying to understand what my professor did on the whiteboard and what the book was expecting on me, and you come up with and make everything so simple and understandable without a simple KCL. Thank you so much for this video!

Thank you so much. My professor has a foreign accent and a silent tone. You have helped clear things up for me in one of my classes.

Dr. Montgomery.... you'r a good man.... thank you

[dorsia]

this video was immensely helpful and I am sad you are not posting videos anymore, regardless I hope you are doing well in your life.

For anyone wanted to see the derivative:
you should get dv(0+)/dt = e^-t * [A1(-WdsinWdt + cosWdt*(0) + A2[WdcosWdt + sinWdt * (0) ] + (A1cosWdt + A2sinWdt) * -e^-t

Plug in zero for t you get:
dv(0+)/dt = A2*Wd + A1(-1)
Or simply
dv(0+)/dt = -A1 + Wd(A2)

I just discovered your video series --GREAT PLEASE ADD MORE!-
It is helping me more than you can imagine.

Do you have any video(s) on worked series RLC examples? Did you know that this is the perfect mathematical theory for such things as MagLevs, and those hobby coilguns all over youtube?


AGAIN, I WOULD LOVE TO SEE MORE RIGHT NOW!

Thank you sir for a good explanation, have enjoyed new steps you've shown.

[nickkenny]

If you took the derivative of v(t) and multiple by c would that be the current thru the capacitor?

[BalkanManic]

Thanks a lot for this explanation. You explain things so clearly.

How to analyse if a step voltage applied to parallel RLC circuit at t=0...?

[shaunk.johnson]

Can you please do more videos on forming the characteristic equations for RLC circuits, 2nd order, forced response, Laplace? Thank you. Your videos are very helpful.

[chrisdettner]

are you writing everything backwards on the board so itll show up normal on our side? O.o

[giziemcbarns]

Aren't all number really the same at the end of the day?

[jrmusan]

Why is it in parallel if the 8ohm resistor is in series with the voltage source?

[jeliotdegolia]

Took me a minute to figure out that he wasn't actually writing backwards, but just mirrored the video.

[ahmetozdemir]

You look this like too easy and simple! Great work! :)

[photon]

what the hell is Wd and how did he get that equation to find Wd

[anthonyn]

you left out the a for the e? should be e^-at

[VitorJTekkRodrigues]

Your arrow is tilted upwards, but the switch moves sideways, that is really confusing...

[celldoublee]

why is the omega d in front of the constant A2 after taking the derivative?
