The circuit is here:

2.the circuit is attached.We need to find I1 I2 and I3

could someone solve these immediately
i have an exam tommorrow  :( :(

halosh92:
is this the answer for question 2?

I1= 0.44
I2=0.39
I3=0.834

?????

astarmathsandphysics:
When I get home

astarmathsandphysics:
V2+V3=3
I2=2I3 whe I2 is current in 2 ohm resistor etc  by symmetry
2I2+3I2=3 so I2=3/5A IA=IB=3/5A
