In this video I will review the general method of solving 1st order RC circuits.
Next video in this series can be seen at:

Man I've been rewatching my professor's lectures all night and they explain it pretty much the exact same way but for some reason it just clicked when you explained it. Thank you!
Glad you find our videos helpful! 🙂
Now that's how to teach ❤
More Grace
Thank you. We appreciate your comment.
@@MichelvanBiezen I have subscribe
Thank you
Now I see why many people prefer the "Step-By-Step Approach" to solve Transient Circuits over the "Differential Approach". Thanks professor!
Different approaches will work, but some are easier than others.
Much better than my college teacher.
Thanks for explanation !
Also wish me good luck for tomorrow's exam 😶, I need it.
Thank you and good luck on your exam!
How’d it go
You’re a good man. Thank you.
honestly, this guy and the the organic teacher, makes math fucking easy. bro, miss literally spent like 4 hours explaining this, literally jump online for 5 mins and find this and bam, makes sense. i don't get unis I swear
Glad you found our videos! 🙂
Best lecture I've found tonight. Thank you, sir!
Thanks a lot sir...
Your outstanding lectures helped me a lot in my exams... 😘😘😘
great content, thanks for the website, it's amazing to have so many units available for free. I appreciate as well the decorations with the American flag and your cool teacher clothes. It looks great and gives a professional look to your videos :)
It also shows respect.
And that's how its done! for sure best explanation. I really like the use of this general strategy as it eliminates
the need to write and solve and new differential equations for every circuit. Textbooks should learn form you.
they should learn to form him?
I quote:"First we find the voltage at the capacitor at t=0. Next we want to know what's the voltage when time has gone by , a lot of time has gone by ,not quite infinity tho because that will take forever".
You dont say!!!!
THat part made me chuckle. Jokes aside tho amazing explanation professor
That was indeed funny. That got me laughing as well!
This guy is amazing
Glad you like the videos.
You are a great teacher
Thank you! 😃
You do a much much better job than my lecturer :) Why am I spending thousands of bucks when I have you?
Cause watching online videos doesn't give you a transcript for employers to look at. So much in the same boat dude.
Sir! I love you!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you. Glad you like our videos.
Why is it that Vc(t=infinity) is understood to take place after switching position? Couldn’t it be in the same position?
Everything else was completely clear, thank you for making this video
sir I am a big fan of your work
Love from Pakistan..
Hi and welcome to the channel!
So do you use this method when two sources are given or can you use this for a single source circuit?
You can use this on a single source circuit as well.
Thank you
You're welcome
the equation you are using is the shortcut for 1st order circuit for dc excitation only. Am I correct?
Great video but quick question, why don't you include the 20V source when finding Vc(infinity)? Is it because all of the current from the 20V source travels through the resistors on the left and to the ground? Or is it more of a conceptual reason?
The switch is moving from left to right, making the capacitor connected to the right side and disconnecting the entire left side. It took me a minute to realize it wasn’t moving up, but rather to the right.
@@Shlivothanks brother!
WE WANT SIGNALS AND SYSTEMS FOR ELECTRICAL ENGİNEERİNG
We plan on covering that in the future.
@@MichelvanBiezen If I may, can u pls specify a certain date? I am planning to enroll in the signal class when you would decide to upload videos.
What's the reason for using this method vs the other?
There are many methods to solve circuits. Here we just show the different methods. When you start practicing this you will choose your favorite method.
Thanks
Welcome
very clear, thanks
At time zero for the left loop isn’t the charge on the capacitor zero so won’t the potential across it also be zero?
Before the switch is moved from the left position to the right position, the capacitor will be fully charged.
@@MichelvanBiezen ah, I was seeing time zero as the assembly of the circuit but your saying time zero is actually after reaching steady state with left circuit closed.
That is the assumption, yes.
Huge thanks prof Michel. One question, what if the second source was less than Vc(t=0), what would happen then? would the source be harmed ?
Note that these examples are just made up in order for us to learn how to handle these type of circuits and don't necessarily represent real circuits. That said, unless the components used cannot handle the voltage or the current, there should be no problem changing the voltage.
Alright, so given that the components could handle such voltages, the capacitor would discharge in the source right ?
ty for the knowledge....
sir, if we had a résistance in the same branche with the capacitor (up the capacitor) is that will have an effect on
final vc? what will happen plz
We have examples like that in later chapters.
Thank you so much.🙃🙃..if you can add subtitles to ur video...it would be very helpful..as english is my third language😶
We are not sure why this video does not have close caption (CC), we'll look into it.
is the voltage 50 at the capacitor at t=(inf) because of KVL?
At time = large, the current in the right mesh will stop when the capacitor is filled with charge, hence there will not be any voltage drop across the resistor and the entire 50 V of the source will be dropped across the capacitor.

Didn't quite understand this comment.
sir i wanted to ask that it is given at time t=0 the switch will move towards right, so how can we consider the circuit for capacitor voltage: the left one??
When the switch is thrown to the right at t=0, the capacitor will be fully charged and the capacitor will temporarily act like a battery.
@@MichelvanBiezen okay thanks alot sir
What does transient exactly mean?
It is the period between the point when the source is turned on and when the final steady state is reached. (That is called the transient period)
sir, how can i get contact to u directly.......i always get ur explanation
The best way to get a hold of us is through these comments. We recommend that you start a new comment (instead of attaching it to an existing comment).
@@MichelvanBiezen thanks sir
V (infinity) = Why would the current not flow through the resistor???
Once the capacitor is charged, no current will flow through the branch on the right (no current through the 5K ohm resistor.
🤟
Hello Professor Biezen, where did the equation from Step Number 2 come from? I tried looking back in the playlist, however, I personally could not find the derivation. Thank you in advance
The voltage in any circuit will always be the sum of the steady state voltage and the transient voltage and the transient voltage is always going to be an exponential decay function as illustrated in the video. You can find more information in the rest of the playlist or here: PHYSICS 48 RC AND RL CIRCUITS
Thanks grandpa
I like that title. 🙂
