Always welcome.

Yes. This happens when X11 forwarding has an issue. Use the -Y switch to force GUI. The command should have such a syntax: ssh -p (your port number) -Y userid@server address. See that -Y, you will have to use this. If it works please report back so that It can be used as a useful resource for many others.

Hi Chris, Your understanding is not entirely correct. Power can be negative, which means the load is actually supplying the power to the system instead of consuming it. This is very much true for many everyday systems. A simplest example to make you understand: a Solar panel (power source) charging a battery (Load), in series to a water heater (another load). Once the battery is fully charged will now supply power (negative power) to the water heater. It is very difficult to explain here in the writing. Secondly, the sign convention used (the direction of the current) will always yield negative or positive power.

@@farazafzl Power due to current flowing in a resistor cannot be negative. Also, if something like a battery is supplying power, it doesn't make the power negative, it becomes a source supplying positive power not a negative load.

@@chrisspain7776You are absolutely correct. But you are missing a concept of the Power absorption/dissipation (by the batteries as well as resistors) and the power generation. Per‍haps you would like to read this www.khanacademy.org/science/electrical-engineering/ee-circuit-analysis-topic/circuit-elements/a/ee-sign-convention Alternatively if you have Hayt and Kemmerly (9th Edition)-- (Example 11.4, Page 439) Or Exercise 14- page 463 and you will understand this concept .

@fzlWhy post that link? The link you provided only talks about conventions for signing of current and voltage, it does not mention power, or support your argument. It doesn't to change the fact that power is always a positive value. If you design a circuit that you claim produces negative power in a resistor, I would keep it to yourself, if I were you :)

If you have DRC errors, then all you have to change the rules and make them more meaningful. What DRC errors are you getting.?

@@farazafzl psubstrate_ stamp error connect and psubstrate stamp error mult. Sir can u pls share your mail id? I will share screen shots. I don't know what to do with those errors.

I am glad that you took motivation. Look for more videos if you want motivation in learning LTSpice, ALtium, Cadence, Transient and Steady state simulations. Good luck

True . .

Thank you for the suggestion. You are absolutely right.

Hi Pablo, If your source is sinusoidal (or any periodic waveform) then just find the voltage at the node as taught in this tutorial. Now hold the "Ctrl" key and left click the mouse on the trace label such as V(vr67) as in 5:04 seconds.

You are welcome

Well, now you know 🙂. Apply the knowledge, spread the word !

Dear Starr, Thank you very much for your comments. I am glad that you liked the video and it has helped you. The video series that I have made are part of the student Lecture/Lab series for one of the Top rated Universities in the World. You found the content helpful having guided instructions unlike other tutorials as the targeted audience are the Undergrad students of the University, just like yourself. Having said that, I would ask you to share the youtube link of the video, instead of uploading it to the other platforms, as it will bring the copyright issues. You could share the link of the whole playlist freely anywhere, but let the content be not copied and shared on other platforms. I hope you will understand my position. Thank you.

@@farazafzal I get it, thanks again for the video series you made！

Hi @Sami saleh, -- It is the "Engineering Circuit Analysis", Eighth Edition, By William Hayt, Jack Kimmerly and Durbin, -- Chapter 8, Example 8.2, Page 266. -- In the 9th edition it happens to be the Example 8.5.

is it arbitrary behavioral voltage source you are talking about ?

You are welcome David. I am glad it was helpful!

This question is from the following book: - Engineering Circuit Analysis 9th Edition by Hayt, Kemmerly (Also present in the 8th Edition) - Example 4.12 - Figure 4.27 - Page 107

It is difficult to say, where did you get it wrong. Perhaps check all the values, as well as time values again and simulate. This should work beyond any doubt.

Check your .model statement correctly

I am glad it was helpful! Keep sharing the knowledge.

I did not get , what you are trying to say. Can you please elaborate more? LPF has one cut-off frequency based on RC values and that cut off frequency occurs when there is a magnitude of 0.707V as clearly defined in the tutorial.

@@farazafzl I means if we have a Band pass filter

- Click Tools-->Control Panel--> - Now Click the tab "Drafting Options" - Here click the Tab towards right "Color Scheme" - From the top select the Tab "Schematic" - Now you will see a drop down menu, select the "Wires" -- Choose color from RGB combinations. For Black All the RGB sliders to Zero.

@@farazafzl Thank you very much for responding Now I got black wire

@@madhavanl3863 You are welcome. I am glad I was able to help.

If you can share the screenshot of your results, I might be able to help you.

@baby boo: Thank you for your comments. 1 -- Regarding 5:06 the phase angle is not important as there is a single sinusoidal source. Every other phase is relative to the source. It becomes important when we have more sources with phase angles. The explanation is here Secondly the video is part of the lab series of a University and always followed by the lab assignments, where students are left to solve few problems at their own end. These kind of detailed explanations take place during the Lab time. Perhaps you would like to see this video from 4:47 th-cam.com/video/_b9Zjg2vP7Y/w-d-xo.html 2 -- Thank you for pointing that out. Well the idea here is to teach every different way of doing things. The videos are part of the lab series where student develop the skills every week and will ultimately be taught the technique you have mentioned. Later in the labs with more advanced concepts this technique becomes a commonplace, however here the teaching requires them to do it manually as part of their learning and the assignments to be followed.

You are welcome Shoaib, I am glad you understood that.
