Dude has been saving my ass since high school, thanks bruv
Will you give something back to him?
@@NoorMohammed-me9lg likes and a sub lol
@@radicalrals9973 haha😂
Thx a ton, saving everyone a lot of time. Now I have time to pursue my passion being a professional yankee candle smeller!!
Very effective class... brother
I feel like hugging you sir may God bless you ❤❤❤❤❤
This helped me today in 2020
less time more knowledge
Howdy. Yeah.
This applies assuming the inductor is lossless, which usually is good enough.
The next level is to see the inductor as a lossy component. The losses can be represented as a resistor either in parallel or in series with an ideal inductor. And observe. The inductance will be slightly different in series than in parallel. The result is astonishing. Theoretically there are two resonant frequencies.
Regards.
Wow you explained it in very less time
Is not the resonant frequency dependent on the source voltage . As to say if you raise the voltage on a series lc the frequency also raises so how is the resonant frequency supposed to remain at 50.3 hz in this scenario???
Amazing! I have a question tho, if that LC circuit is pulsed using a transistor, let's say 2N2222, which has a frequency around 250000 Hz, if I want this oscillator circuit to resonate, how? should the LC frequency match the transistor frequency, so I'll have to change the coil and/or the capacitor fore new L/C?
Sorry I'm an electronic newbie trying to learn more.
You might want to use a pwm circuit to pulse it.
This video actually what I am looking for ❤❤❤ TQ
How do you put this in a calculator
Incredible job my dear sir 😅
There are so many people showing how to plug the numbers.
There are an infinite number of LC pairs for every single frequency.
Do you know how to choose which pair to use, in specific circuit situations?
How does this work for
parallel LC : High impedance?
series LC : Low impedance?
What affect does source voltage and power capability play in the selection?
You calculate base on the load and frequency at which your circuit will work at. The lower the capacitance of a ceramic capacitor the lower the impedance at high frequency. That information is given in the datasheet, if you are using a 12mhz mcu look for a capacitor with the lower impedance at 12 mhz then calculate the value of L by replacing the C for the actual value of the capacitor then solve for L. I hope this helps. There is also a formula for ripple base on your load if you search for it. Look for "EEVblog #859 - Bypass Capacitor Tutorial" close to the end of the video he uses an analyzer to measure impedance with difference decupling capacitors.
Thank u!
So, for a resonant frequency in which the only elements are a capacitor and an inductor - does this mean that the resonant frequency is the frequency that can traverse both the capacitor and the inductor in series to the other side of the circuit?
Thanks
Will the equation be the same for LC parallel circuit?
I believe so, but at resonant frequency one circuit acts as a short and the other an open circuit
This will be useful for science olympiad please reply
Im trying to understand how to use excel to do this and show me a graph similar to a breakeven chart where line for Xl crosses Xc line at say 455 khz to construct BFO's for use in my shortwave radios.
what would i do without you pookie💔
In this if we want to find capacitance then it should have the same formula or different if it is same what we had change to get capacitance?
Thank you
hi, how to find C for exemple if u just know L but you have to solve resonant frequency, how do i can find C?
I want to figure out what the antenna impedance is when connected to a matching circuit. The antenna connects to a LC circuit. The series inductor connects to the antenna. The other side of the inductor has a capacitor to gnd. I know the value of the inductor, capacitor. The transmitter is 50 ohms and the frequency is 3.573MHz. With these values I have no SWR. What is the impedance of the antenna? The transmitter connects at the LC junction to ground. Would you know of a calculator program ?
Sir when to use 1/2Π√LC AND to use 1/√LC IM GETTING CONFUSED WHILE SOLVING problems
One is in parallel and the other one is in series.
This hepled me in Dec. 2020
What would be the resonance frequency if capacitance and inductance is double ...?????😮
Thanks
Could you show us what you pressed on the calculator?
no
So nice
What would be the power factor at that frequency be in the circuit?
Thank you mate you are truly the best tutor great work dude.
Does this mean if I built a crystal radio I can only move down channels? If so I built the antenna too big or something.
Thank you😘
How about a video on how to input that on a scientific calculator?
Get an HP Prime, it does pretty much everything, and even has python now.
@@secondjar why not ti84 ?
heh.. jak jednoduché 😃
chci umřít D:
Im given a question:
"Design a LC tunned circuit at 674 KHz."
only this much. Can someone help.?
maybe it wants you to select capacitance and inductance values which will make it work?
Cool
what is that 11 down votes . this couldnt be explained any better .
How does he know so much???
That number depends on where you put the ground wire On the circuit negative side positive side or in between the C and L.
As a indian it looks so frustation to do it step by step,
We usually do it in 1-2 steps 😅❤️
i am just trying to under stand how to find resonance frequency I DONT KNOW THESE FORMULA OR THE MEANING OF PI I HAVENT LEARNED THEN I JUST WANT SOMEONE TO ESPLAIN IN SIMPLE TERMS NOT THESE COMPLEX FORMULA
nice to share - except i heard there a lot of key clicks from about 2min on - - this is because the answer is incomplete and you didn't explain the rest of it ??
He was typing it into a calculator
:)
i still dont understand this mess
Pronounce Property sir 😒
Seems like the long way to the answer
thanks
