Find the i1 and the power dissipated in 10 resistor ohms

## Homework Equations

P=I^2 x R

P= I x E

Ohms law

E= I x R

## The Attempt at a Solution

@node A I=-i2 +Io

@node B i2=-i1-i3

@node C Io=i4-i3

@node D I=i1 + i4

Im trying to solve for the R total, to find the I total and find the individual Current in the resistor.. but im having trouble in determining which in the circuit is in parallel and series

i came with this answer when i try my work

P=66.04

but my prof gave me a range of 570 - 650 ... my calculation is wrong

anyone who can help?
