For 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.

Good man @marconi
 
For my EF colleagues: 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.

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).

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 know

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???

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.

This is part my question???
You give me extra work ???????
I turn off my laptop now , but later maybe thinking about ???
