Are you still working your twelve hour days and trying to fit all this in.
If that is the case then I can't see how it's going to be possible.

No mate , COV19.Are you still working your twelve hour days and trying to fit all this in.
Good man @marconiFor my esteemed EF colleagues: I am now in dialogue with Zaprinski in the PM area. He has sent me all his answers to the questions he has completed which I am reading through and commenting on - not doing for him.
Generally the presentation of his answers is very good. Some silly mistakes and some misunderstandings but for his stage of education and training I think he is 'up with the hunt'. We are working through a better understanding by him of phasors and how they can be used to present ac quantities and how to correctly label, interpret and construct them.
In #1 Q4a the question asks the candidate to work out the magnitude of the neutral current in an unbalanced 3 phase 4 wire unbalanced system.
I don’t know , but I understand know
Could those that have been to college recently and used phasors and the geometrical method tell me whether the candidate is expected to show on his/her phasor diagram that In is in antiphase to L1 + L2 + L3?
Or are the examiners content that the resultant current phasor L1 + L2 + L3 has been constructed geometrically correctly?
I don’t know but I understand geometry, how to work out , neutral current, In but spend lots time for this question.
Some my people in the College, they pay someone to do Assignment.
I need to help but , When my tutor ask where the get from answers???
This is part my question???You have set yourself up for another question! I thought we agreed we both needed a break
If In is actually (and it is) in antiphase to L1 + L2 + L3 draw the phasor for it on your last diagram that you sent me.
I need to use this line on my boss.You give me extra work ???????
I turn off my laptop now

Could those that have been to college recently and used phasors and the geometrical method tell me whether the candidate is expected to show on his/her phasor diagram that In is in antiphase to L1 + L2 + L3? (cf Kirchoff's first law).

I nearly done half assignment.???You have set yourself up for another question! I thought we agreed we both needed a break

Nice one Zaprinski.
For the amusement of all those EF members wanting something to think
Look at the OPs paper and Q4a. An unbalanced set of currents. How could you simplify this phasor diagram to two phasors straightaway? And then find the resultant of these two? Post your work
??? Good answer mate .I believe you can use SOHCAHTOA (specifically CAH) to combine two that would greatly simplify the diagram, and the numbers are nice too. I'm thinking L2 and L3.
After giving the question ALOT of consideration I’ve come to the conclusion that I’d probably beg and plead with yourself and or @Lucien Nunes for help ?For the amusement of all those EF members wanting something to think about:
