    hi gays:
    I need your help to solve some question:

    three-phase circuit (topic)
    1-In wye(Y) connected circuit,if the line to line voltage is X or 346 (for example).What is the line to line neutral voltage?
    2-In delta connected circuit,the current is X or 20A (for example).in each resistance load. What is the line current?
    3-In wye(Y) connected circuit, the current is 10A in each resistance load.Whar is the line current?
    4-three loads each having a resistance of 10 ohms are connected in (Y). the total three phase power 3000W. What is the line to line voltageof the power supply?
    5-three resistors each having a resistance of 11 ohms are connected in Delta across a 3Ф 440volt line :
    • What is the line current?
    • What is the total three phase power?

    please solve with explaintion

    Try again. What you need is indeed in there: http://www.allaboutcircuits.com/vol_2/chpt_10/5.html
    I'm sorry, but it is against our policy to provide direct answers to homework questions. If you don't do your own work, you will learn nothing. Such would defeat the whole purpose of school, yes?
