How to Calculate Circuit Efficiency
This tutorial demonstrates how to calculate overall circuit efficiency. This considers line drop and line loss in the conductors themselves to determine how much power is being put into the circuit and how much is being output at the actual load.
This video is part of a full free course on electric circuits. The course covers DC circuits, circuit laws, current & voltage sources, series & parallel resistors, nodal analysis, mesh analysis, and AC circuits.

Resistor Resistance Rating Codes
Просмотров 3147 месяцев назад
Resistors sometimes use a letter and some digits to designate the resistance. The letter, and it's position are significant in their telling of what the resistance is.

Excellent work
Its incredible thankyou. Here i am in 2024❤
This was excellent! Thank you.
5:27 arent theese parallel?
What if u have a voltage source in the middle do u just add it like normal
Sir, my lecturer teach me to use kcl and kvl at super node is it correct? I'm confuse.
Thanks
😢eyy finally found it easier than in class
can u pls do a vice versa? where u will make v(s) into a(s) pls pls pls
what if it's v(s) ?? how can i solve it
Thank you my hero!!!
Question, does activity B start on day 6 or 5? Because it takes 5 days to finish activity A, then the following NEXT day to start activity B? So is Early start for B, 5 days or 6 days?
Thanks, this really helped!!!👍
Thank you
free body diagram 0:58 distance from A to W(x) is half L not (X/2)...which i think affects the sum of moments and 0ther equ(s)...let me Kn0w wats up!
Thank u
Which textbook do you recommend for this course
super super super super super super super super super super super super helpful as a someone with no project management knowledge
Best ever 👍
Why didn't you considered four nodes instead of three
Am I the only one who got the values of A,B and C as 1.625, 0.5625 and -1.1875 ?
bro explained it better than college professor
Thank You
Great
his voice is irritating just giving asmr
Thank you so much sir❤
Why 98.1 can you please explain, I am dumb ik
Cuz T = mg, where m is 10kg hence when we take g as 9.81 ms² the tension would be 98.1 N
Anyone clarify me if we consider I under 2 in opposite direction wether the equation Kcl A is messed or not
i tried struct ->vector -> vector
You just saved me from reading 100 page pdf of gibberish my lecturer had given ❤ Very grateful 🙏
Godbless you for this
the video has minor mistakes
there is a problem here. you are supposed to add 1 to the early start
I've been learning CPM to help my student and PDM is a lot easier for me than CPM. Your other video is the best illustration of PDM that I've seen and I've been searching a lot. This video demonstrates how much clumsier CPM is than PDM. Thank you.
i dont get v3// why not (1-1.43)
you got an answer yet?
Incorrect
Thank you for taking the time to make this video. My class textbook doesn't break down how it arrives at these numbers. It does a horrible job of explaining. I'm blessed that I found your video!
thNk tyou
quick question , sorry if its a stupid one , but how do you know whether to use cosine or sine when finding out the forces? thanks
Tnq so much ❤
❤
if one activity cannot start until another finishes then that is the next day. The ES for C and B should be 4 since A completes on day 3. Also, I dont agree that an activity day starts on day zero in reality, it begins on day 1. Thus, throwing off this entire schedule before even moving onto the 2nd activity(s).
Also, the explanation for CP completely skips over float and misses an opportunity to better identify CP.
Thank you... informative and straightforward... you made it simple... all the best
why does activity B have Incurred cost of 1400 and not 1200?
Thank you, my note did a horrible job
Thank you
explained in simple manner
Thank you 🙏🏿🙏🏿
holy cow this is such a good explanation!
Waoh, so easy . Thanks for explaining in a simple way. Teaching shouldn't be difficult.
