Phasor Diagram Current in the Neutral
A short demo with no sound on how to create a phasor diagram to determine the current flowing in the neutral wire of an unbalanced 3 phase system. The demo assumes all phases are in unity.

Current flow is a circuit with two power supplies. Type of question found in Engineering BTEC questions for unit 1, 5 and 28.
Formula wheel is very helpful. How clever of you. Now I clearly understand. Thank you so much. God bless you my teacher.
Hi sir, question, how about the given is voltage secondary,turns secondary and frequenzy?hiw to find number of turns and voltage of primary?
How many amps in 240vac input? Still confused
Does R resistance are measured on -load or without load ?
im not sure why but transposing just isnt sinking in for me
You said pp, brilliant
Plumber here
Thank you!
This is NOT solving a transformer. These crude basic formulas of turns ratio do nothing to calculate transformer inductances which is what its all about. Further, baluns have no place in modern ham radio, baluns are for coupling open and concentric lines, NOT FOR ANTENNAS. There is no excuse for using twin lead with low resistance antennas, coax is so cheap to buy. This info is trivial and useless
sir you make a video on calculate of the following namely .1. turn per volt 2.wire size calculation for both primary and secondary side of transformer 3.cross section area of transformer core etc.all these calculation related to E I type core transformer.
Where does 7.79 come from
I can do basic versions of these but never know where to start with larger ones, I want to find c in vc = vs( 1-e -t/rc ) I don't want to avoid this, I want to learn but I have to understand
well, nice explained, but you never named, what is 12.and what is the ratio? is it 12
Hey how did the 10to the power of 3 come into it exactly and the 10to the power of 6? Can someone please explain
👌
super
The best video about transformers
This a nice video... Thank u
I've never seen this done the same way twice. By any teacher in high school, any lecturer in college, by any engineer in the field or any tutor on youtube. The sheer number of ways to do this is astounding.
Thank you for a great clear concise explanation from a to b & c thank you wonderful may God bless you brother thanx again
So helpful. Thank you!
I finished GCSE maths with a Grade C. I always struggled with Transposition and I'm now training to do a Electrical engineering qualification and I was able to calculate the volume of v2 to 0.5m3 your help on the first go! Thank you so much!
HI Mike, (Darren Crouch) Loved your classes and so chuffed you have this channel. Really useful. Hope life is treating you well
Hi Mike, thanks very much for making this video. It really helped me to study for the test I needed to do to enrol in an Electrotechnology course. I like to think that I passed because of you! I really needed this video after being out of secondary schooling for many months.
Knowing the basics is the most important in electrical engineering. Well- explained sir..Shout out and God bless
As soon as you have Vp and Vs calculated 240/20 is a ratio of 1/12 - so either divide or multiply by 12 on Ip and Np. Or is there a situation where this would become invalid seen as we are using a balanced equation.
Electrician over here
same lol
Hello from 2021. I will use this video to help pass an upcoming exam. Side-note: you said “pp” :)
Interesting
Is it not -27 or +332, then by adding +180 we get +153? If not, please can you explain this to me?
The only thing missing from this video is that number of turns does NOT = resistance. You have to select a specific gauge wire x length of wire to get resistance.
One parameter is missing.....no load current !! How I can calculate ??
This is really useful!
in the example c=q/v why can't you just get q to the other side first and be done?
I think hes just showing the full version to get an idea, later on you can mix and match.
ATTA BOY, THANKS- VERY CLEAR AND thorough- highly appreciated lesson.
thannnnks so much.
Awesome explanation!
Very helpful thanks
Thank you. This is extremely helpful.
This helped a heap, thank you Mike.
Very interesting and informative sir
Please show me how to calculate the wire size for the 5 volt dc power Thanks very much
RIGHT ON thank you
pretty stupid, great start and then you refer to a wheel which wouldn't be in an exam paper. If you explained how to individually work out vp, vs, ns, np and ip, is that would help everyone. Im aware its cross multiply but theres 6 in the formula so crossing is confusing
Extremely interesting, well structured and a lovely speaking voice.
Brilliant!
Well done and great explanation thank you!!!
i wish you would explain without the formula wheel which we aren't going to have in an exam
Memorize it.
very good explanation!
Well done, thank you
