Great demo done in a way that is practical for anyone to duplicate and learn. Also, great way to lock down the lab in equipment with chains. Thank you.
Excellent video it is one of the best i have seen,you have explained perfectly. Are there any more, so that I can learn and understand Ac circuits. Thank you.
Im looking for this but plotted on an excel chart to interactively change the values and have excell calculate this way faster than doing this by hand. Anyone know how?
In AC there is no positive or negative. That should be live and neutral. The color of the wires used on breadboard is supposed to be black and white( it may vary country to country)
Abdul Kadhar Thank you for watching my video and your valuable comment. I'm so happy. We use here red and black wires to represent positive and negative respectively. The input is taken from function generator that has red and black leads. To keep the students out of confusion with respect to terminology and the color codes, I used the terms positive and negative while connecting. The DMM leads are again red and black marked as positive and common. I explain to students that the polarities of the terminals switch from positive to negative and back continuously when supplied with AC signal. Thank you for bringing this up.
+Bhuvana Sriganesh Basically, the resonant frequency is the same for both series and parallel circuits. The difference is voltage across the resistor is maximum at resonant frequency in a series circuit and minimum in a parallel circuit.
please i have two questions: how much voltage increase in across inductor in resonance case is the difference between using ac or dc current in resonance case?
Do you know one important thing about resonance? When R, L and C are connected in series with a variable ac power supply, at a particular frequency called resonant frequency, voltage across L and C would be equal. Since they are acting in opposite directions (recollect from the phasor diagram - Vc on negative imaginary axis and VL on positive imaginary axis), they cancel each other. At this frequency, XL = Xc that cancel off and total impedance of the circuit is just R. Since impedance is min = R, I is max at resonance in a series circuit. Since L and C allow AC signals to flow freely through them and block DC, you wouldn't be able to study the effect of resonance with DC supply. Now research about parallel RLC and come back if you have questions.
This video is great, but I think the calibration of some values of the components are wrong since they don't line up any where close to theoretical? Voltages are much too low at resonance.
hello mam can the battery terminals be directly connected to R and then calculate the impedance for the battery ?.....i have a lead acid battery for which i need to calculate the impedance over range of frequencies.... Thank you

Hand writing is clear .Thanks for good teaching.
Thank you. Very good video and perfect explanation. But i am so curious to know what is that metallic chain around the eauipment?!

Excellent

Series Resonance is at the top peak of the first curve and parallel resonance at the bottom peak of the second.
Please open machine translation subtitles
Thank you
Thanks so much mam, this is really helpfull.
well explained
Thankyou for uploading this..
Mame ,
good job .....

thanks alot for this video
but practically you mean the resonance is at the bottom or the top of peak in curves?
+new man Resonant Frequency of a parallel circuit is at the bottom and for a series circuit, it's on top. Thanks for watching and your question.
can i add you on facebook?

Because of confusion I made a parallel board instead of series in my practical 😂

Thank you
Video is not clear of R L C Series circuit
kya bat hai babe
which university/college are you from?
This recording was done at Centennial College in Toronto Canada.
Oh okay.. I sort of guessed that this couldn't have been India. Thanks for letting me know.
