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.

Most superb explanation of the forward and backward pass.
why do we put a dummy node in the first example? can we not make it without the dummy node?
Thank you! Love you! You made it simple

Bro .. when I tell u .. u just saved my Life.. and I want to thank u🎉 explained this so well Preciate u
is the man still alive 2024?
❤❤❤❤❤ Excellent 👌 you explain it well, thank you ❤❤❤
What happens when we was 30% ofproject completion ? There is no 0.30 in the table. Any ideas ? I have my exams on the subject on 11/7/2024, wish me luck :)
why is dV = dAdx, not just dV = Adx? 1:31
you are the best, thank you
Please where will I create this graph from my system?
thankyou so much .i hv a doubt.if the shear force at the rightmost end is -50N,it implies that shear force at right most end is 50 N vertically upwards .so when considering vertical forces at B.it should add up to a net force of Rb+Sb=50+50=100.then how could B be at rest
thanks
Youre amazing
Thanks Shana 😊
Thanks
No problem🙂
Thank you🙏
You’re welcome 😊
I wish I saw this video 4 years ago. this will be my go to video every time I'm having a brain dead moment
Why didn't you multiply the area by 2?
you are amazing thank you
Thank you to the comments... I was like HOW TF is it $3,200?! lol Great information tho!
Such a nice explanation, thumbs up
Glad you liked it! 😊
thanks for the tutorial, It's easier to be understood than what I've been taught in my class
I friggin love you! Been watching your videos, you saved my life!
Love you too ❤️
7yr ago and I'm heir watching 😅

Sir, I've just finished your lessons that you taught us. They all are so clear to understand and thank you so much sir. I'd like to request you to teach us about Microsoft Project or Primavera P6 sir.
Theory tests might require rounding to 3 sf so maybe calculate in 5sf? As i got 1.520 ohms when calculation by myself. Great video though
well explain , thank you.
why 5 nodes? Node is a point where 2 or more elements are combined, so in this example it should be 4 nodes.
DAMN
Very informative simplified video. Thank you ❤️
Very helpful. Thank you. keep making such videos.
Is the parabolic curve always upwards and never downwards? I'm speaking to when you draw the parabolic curve between two points.
Clear and consice. Needed a refresher and you did a great job. Thanks!
Sher gut❤
In case one or all power sources has internal resistance, how can we solve the problem?
Can we apply this method no matter what function we have ?
Any jee aspirant..?
I’m in love with you
Thank you!
After 9 Years...... Your videos are so much understandable.
Thank you so much!👍🏻
Wow it finally makes sense 🎉
if ay and ma are positive, why has it been drawn in the negative?
Well done 😊😊thnkkuuuu alot
