Resonant Frequency of LC Circuits - Physics

This physics video tutorial on AC circuits explains how to calculate the resonant frequency of LC circuits using a simple formula. LC circuits are circuits containing only inductors and capacitors.

Dude has been saving my ass since high school, thanks bruv

[jonyypineapple]

Thx a ton, saving everyone a lot of time. Now I have time to pursue my passion being a professional yankee candle smeller!!

[alimanchua]

This video actually what I am looking for ❤❤❤ TQ

[omsingharjit]

Wow you explained it in very less time

[Educationaccount]

Thank you mate you are truly the best tutor great work dude.

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?

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 ?

[Foxhole]

What would be the power factor at that frequency be in the circuit?

[mykedoes]

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???

[Slowly_Going_Mad]

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.

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?

[necarforever]

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.

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?

[marksebastian]

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?

[eugenepohjola]

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.

This will be useful for science olympiad please reply

[UpcomingJedi]

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.

[unrealproduction]

Will the equation be the same for LC parallel circuit?

[rangaswamy]

Sir when to use 1/2Π√LC AND to use 1/√LC IM GETTING CONFUSED WHILE SOLVING problems

[pikazap]

heh.. jak jednoduché 😃
