As an electrician this is great video to brush up on theory. Great work !

[@stepbystepscience]

Great to know and thanks for watching and commenting.

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

[@stepbystepscience]

Thanks for the great comment.

[@alejandroalmarza8447]

Excellent explanation….very detailed and crystal clear ….thanks

[@stepbystepscience]

You are very welcome!

[@aliabdi7630]

tremendous job, this is something I never see before,

[@stepbystepscience]

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]

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

[@andrewfortus2629]

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 :)

[@stepbystepscience]

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

Welcome

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?

[@stepbystepscience]

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

[@GymChess]

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

[@asandamvusongobese2109]

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

[@seanarsenault6097]

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

[@mahsumoral4960]

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

[@marvik666]

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

[@ronvaliant9337]

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]

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

[@stepbystepscience]

I can look into it.

[@rohan_nyc]

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

[@theherheoroie]

Very helpful

[@stepbystepscience]

Glad to hear that

[@sachinrath219]

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

[@stepbystepscience]

No

[@khatarinakramer7145]

What if there are multiple resistors and capacitors and inductors

[@stepbystepscience]

Then it gets very complicated

[@havard8031]

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

[@stepbystepscience]

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

[@kissdarren4233]

Greeting please I have a problem don't know if you could be of help

[@stepbystepscience]

What is the problem?
