Calculating Phase & Line Current

[shnabz2]

< Mentor Note -- thread moved from EE to the Homework Help forums >

I'm studying for a Level 3 Diploma in Electro technical science. My tutor had a hard time teaching me what I need to know in order to answer this question;

Calculate the phase and line current when three resistors each having a resistance of 15Ω are connected, to a 400 V three-phase supply, in
A) Star (Wye)
B) Delta

Could someone show me the steps involved in solving this please.

Thanks for your attempt, however this is just as useless as my tutor. I don't need help finding information. I need help applying the information to a real scenario. The formulae's in the link you gave me show the relationship between Phase/Line current. What I'm having trouble with is actually getting a value in the first place.

All the formulae you need for solving this simple example you can find in the link. It seems you have problem with understanding and applying formulae. Better you forward to HW section then: https://www.physicsforums.com/forums/engineering-comp-sci-technology-homework.158/
I won't calculate it for you, but people will help you there.
