For parallel RLC circuits goes over an example problem for how to draw the current phasor diagram, the admittance triangle and how to determine the phase angle between the current and the voltage. Also how to calculate the total current and the impedance of the circuit.

1 comprehensive and fun science video by step-by-step science channel = 1 whole term of a boring university course

@stepbystepscience 4 года назад

Thanks for the great comment.

tremendous job, this is something I never see before,

@stepbystepscience 4 года назад

Glad you like it and thanks fo the comment.

I'm confused. I was told that the inductor is always positive 90 degrees and the capacitor is always -90 degrees. But in your Current calculations it's the opposite. Why? 4:50

@Festus2022 3 месяца назад

Nice video: One question that no one ever addresses is WHERE does the transition from one current to another occur? For instance, where exactly does the 1.56amp, 11-degree, Total current transition to the 1.52amp, zero degree current through the resister? Does this occur inside the passive element or in the wire before/after the passive element? Thanks

In series RLC circuit, why the scope of 𝑉R vs. 𝑉out graph is displayed as an oval loop?

@andrewfortus2629 4 года назад

Thank you for the series I went through all 19 and will go through more. At 11:04 I think it's supposed to be (Bc-Bl)^2 under the square root for total admittance? Thanks again! EDIT: NEVERMIND ! I see now you are adding them up VECTORILY :)

Great that found the videos helpful and thank you very much for commenting.

Cosine instead of tan: 1,53/1,56 equals almost the same - 11 degrees.

@asandamvusongobese2109 Год назад

would you advase me to to solve using angular form??

@marvik666 2 года назад

Hello just started watching you doing numbers if I may ask you to do some rlc circuit in serials also iam just stated to do rlr and RLCR R RESISTOR L INDUCTOR C CAPACITOR if you can please do a Capple of video like this please I thank you very much Kindl regards Anthony

@seanarsenault6097 2 года назад

What if R is in series and C and L are in parallel? Whats the formula then?

@LuferXVII 8 месяцев назад

Hello, I have a question about knowing the phase angle in the source voltage, can I determine an angle φ according to the impedance values and then do Ohm's Law, please see the equation I made and if it is coherent. Z=147 ohm, φ=tan^-1(((259-193)/(150)))=23.7495. IT= 1.56 A φ= 11 ... V=Z*I V=147*1.56= 229.32 V φ= 23.7495+11=34.7495 V=229.32 ∠ 34.7495....ok?

I don't really have time to evaluate the details of this problem, sorry.

@sachinrath219 3 года назад

when current lags the voltage,does it mean it flows in the reverse direction to the one taken in the resistor.

@ronvaliant9337 3 года назад

I was taught that if the reactance was inductive it was positive and if it was capacitive it was negative. And it 's the reactance instead of current. Is this wrong?

@rohan_nyc 4 года назад

Again nice video 👍. Can you please solve the problem taking polar angles into consideration. Z=R+jX and Y=G+jB.

@stepbystepscience 4 года назад

I can look into it.

@rohan_nyc 4 года назад

@@stepbystepscience Thank you so much. Im looking forward to watch the video:)

@havard8031 4 года назад

Can you explain the formula Zt = 1/sqrt(1/R^2 + (1/Xl - 1/Xc)^2)?

@stepbystepscience 4 года назад

I could make a video about it but mean time check out this page: under "Impedance of a Parallel RLC Circuit" www.electronics-tutorials.ws/accircuits/parallel-circuit.html
