Professor Organic Chemistry Tutor, thank you for a short Introduction into Impendence in Applied/Engineering Physics. Impendence is really tied to AC Circuits. Professor Organic Chemistry Tutor, thanks to the viewers for finding and correcting the error(s) in this video.
For everyone's reference the first example should have an impedance of 664.4 due to the resistor alue being 400 and not 100 ohms, hope this helps! the coressponding current value should be 0.181 A
Yup, I love you. Thank you for being a boss on all the levels. So many would benifit from a basic understanding of electronics. And math. And chemistry. And. And. And...
Yes an error--- 400/100 ohms GOOD VIDEOS--- YOU DO A EXCELLENT JOB. It intuitively seems to me that the resonant frequency should be a highly desirable state for any circuit. YES/ NO?
Great job comparing and contrasting resistance, capacitive reactance, inductive reactance and impedence. I wish though he explained why the resonance frequency is important. At resonance, XL equals XC, meaning they cancel each other out. This leaves the impedance of the circuit to be purely resistive. As a result, the current that flows through the series RLC circuit is at its peak when it’s operating at its resonant frequency.
Thank you for this video. My basic electrical book didn't explain things in a way for me to understand the formulas. The definitions helped me out too. Thanks. 👍
2πf is also known as angular speed in rad/s, the symbol is ω. Therefore you can write XL=ωL or XC=1/ωC. Dont worry about 400 or 100 ohms, simply put 100 ohms on the schematic and reply will be true.
Absolutely fantastic video. Thank you very much! Would it be possible to provide a real life example in the form of guitar amplifiers? Amp heads 'need'to match with the impedance of the cabinet (speakers). Could you please create a video explaining the reason why they need to match and what could happen if they do not match? Thank you very much Julio. You have been a great inspiration to me. A loyal fan from Belfast, Ireland
It helps to think of impedance as a local quantity that relates to 2 sinusoidal quantities in the complex plane represented as phasors. Those 2 sinusoidal quantities being voltage drop across and current thru a capacitor or inductor or resistor. Because impedance is an ohm's law based quantity it's expression for inductor has j in it (voltage leads current) and has -j in expression for capacitor (voltage lags current).
In the diagram you show -400 ohhs resistor but you use a 100 ohms resistor to do the calculations when had to be 400 ohms to get the correct impedance ....the procedure is correct but the calculations are wrong....... any how nice video tnks de Kp4 BP...P.R

An inductor with a value of 30 ohms, a resistor with a value of 40 ohms, and a 25 ohm capacitor are connected to 220 V, 60 Hz power supply. Solve for the Impedance and the Current.

Impedance approx. 664.402 ohms (error was R = 100 ohms instead of 400 Ohms), Rms current = 0.181A
thank you buddy
I thought I went crazy for a while, thanks!
thankyou
thanks so much bro, i was freaking out like mad haha
Thanks bro i was about to destroy my calculator
Hi, in your first example the resistor in the schematic is 400 ohms but you used 100 ohms in the calculations.Everything else is perfect.
I noticed that. Simple mistake...yet confusing for my simple brain!
Thanks mate thought that was an error!
Yeah. And no explanation from this so-called"Tutor" as to why that is/was? Whoopsie! WAI
Yes exactly
This should be edit, as it will make confuse to all of students around the world.

thank you for being straight to the point. This helps alot as i found it confusing to understand what my teacher was explaining in class lol
My instructor made my head hurt. So I came to this video. And I'm very grateful that I did.
Thank you for this video. My basic electrical book didn't explain things in a way for me to understand the formulas. The definitions helped me out too. Thanks. 👍
A hard to understand and complicated explanation of something that is not really terribly difficult.
So wonderfully simplified. Thanks!
Excellent video! Made this really easy. Thanks!
Never thought my Electrical Engineering course will be saved by an Organic Chemistry tutor.
why did you use 100 ohms instead of 400 ohms in the first example ? :)
i did notice that also.
2πf is also known as angular speed in rad/s, the symbol is ω. Therefore you can write XL=ωL or XC=1/ωC.

thx bro . quick and actualy useful explanation.
Sir thanks to you
I have understood Impedance
good teacher. all teacher remuneration should be tied to exam scores.
Thanks sir you really made it clear for me...am comfortable now
VERY NICE EXPLANATION THANK YOU
Amazing explanation and examples! Thank you so much.
Your videos safe life sir ,thanks a lot 🥰🙏🤲
Its very helpful 🙏 thank you so much....
It's really helpful content
I don't watch my prof teaching videos, instead I watch yours for a better understanding

Thanks Professor✊u re the best
thank you very much
Thank you sir good explanation
is this formula valid when we have impedance in phasors or only if we don't have complex operator ?
I've seen the formula Z = R + jX before, is that similar?
Does it matter which comes first in the formula xl and xc? or does
Who are you, what are you, are you sent by god?! I'm .... bruh just thank you so very very very much

2:45 where is this frequency coming from that will determine these things?
Very helpful! Thank you!
Amazing Viddeo Thank you!
Nice video
thanks 😍😍
So nice
Thanks a lot sir 🎉❤
Good video please explain about fR
Great explanation, can you please do another video of power plant generator related to capacitance reactance and inductive reaction
Hi, I like your lecture
perfect thank you very much
These examples are all in series. Does it matter if some components are in parallel?
Thank you❤
I need to know how to get total impedence from just the R Xl and CL numbers froman RLC parallel?
what about when you are not given the frequency?
Thank you
What about the j values? I was also taught to add the impedance when in series. I’ve never seen that formula.
How do I calculate Impedance if the power taken by an inductive load when connected to a 120V, 50Hz supply is 400W & current of 8A
5:36 When you can no longer read your own writing, then it's time to write more beautifully. 100 is wrong, it should be 400.^^
Error in second example. For the calculations of XL.
Based teacher
Is there an example on how to calculate the impedance in an RLC parallel cicruit?
is your videos for uni or high school physics
I don't understand why in some videos reactance of Xc is -1/wC and in some other just 1/wC. I even saw -j/wC...
This is the 2nd video in a row with miscalculations. That is ridiculous!
my answer is 180.61mA, i did not use (0-Xc)^2 but instead i used (Xc)^2 directly in finding the impedance. Can someone correct me though?
Why (XL-Xc)?
How to calculate impedance in calculator
You're literally the only thing between me and failure
U could have used the formula for a circuit with resistance and capacitance only leaving out the inductance.
yes only understand,but its correct
the answer on the first example should be 0.1806A or 180.6mA
100 instead of 400 ohm , what will be the answer?
I'd like to ask if the current we find at 9:10 is the Irms or the Ipeak.
Irms
in, the first example, you take R=400 Ohms, but in the calculation you substituted 100 Ohms. Plz correct it
In the diagram you show -400 ohhs resistor but you use a 100 ohms resistor to do the calculations when had to be 400 ohms to
get the correct impedance ....the procedure is correct but the calculations are wrong....... any how nice video
tnks de Kp4 BP...P.R
The mistake of using 100 ohms i guess was changed from the original stated 400 ohm in the problem

And what about capacitor and inductor in DC circuit?!! please help
in dc stuff isn't that complicated it's pretty much just ohms of the circuit added together to calculate the current U / R = I . it's really easy
400 squared
I was picking up everything until you got to the 10 to the -6 ugh backtracking time

Was thinking i was loosing it with 100ohms till i chkd comments

Big mistake please correct it
Watching this while having a test in a matter of minutes, guess it's my fault not coming sooner😑😪
resistance is 400 ohms and not 100 ohms on the circuit
what does Vrms mean?
The average magnitude of the voltage. V_p/(root 2)
