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.
