    HERE IS A NODE ANALYSIS QUESTION:
    IN COMPLEX NETWORK THERE ARE FIVE BRANCHES AND TWO VOLTAGE SOURCES.
    I FOUND V1 AND V2 BUT NOT CURRENTS IN EACH RESISTOR YET
    GIVEN THAT:
    R1 = 2 Ω
    R2 = 2 Ω
    R3 = 3 Ω
    R4 = 6 Ω
    R5 = 6 Ω
    E1 = 2 VOLTS
    E2 = 2 VOLTS

    I FOUND THE EQUATIONS BY NODE ANALYSIS

    EQUATION 1 IS (V1/R2)+(V1-E1/R1)+(V1-V2/R3)=0

    WHICH IS AFTER SOLVING BY PUTTING VALUES

    4V1-V2=3----------EQ:1

    EQUATION 2 IS (V2/R4)+(V2-V1/R3)+(V2+E2/R5)=0

    WHICH IS AFTER SOLVING BY PUTTING VALUES

    V1-2V2=1------------EQ:2

    AFTER SIMULTANEOUSLY SOLVING EQUATIONS

    V1=5/7 VOLTS

    V2=-1/7 VOLTS

    NOW I WANT TO FIND CURRENTS IN EACH RESISTOR SO PLZ HELP ME OUT
    BY FINDING CURRENTS IN ALL BRANCHES

    Is this a homework question? If so, let me know so I can move it into the homework section.

    Can you post a sketch of your circuit? It will insure that all of the members are clear on what it looks like.

    Without the sketch, how does one know how the resistors and the voltage sources are connected?
