well multisim understands it... i don't know what type of course you are learning this in... but assume you can break down a series parallel circuit... try it like this... 2 charts fill in the missing information... V I R R2 1.23v 153.85mA 8 R3 461.54mV...

yeah you got it! most useless circuit ever... Haven't been able to find any real world examples where that is used... just made to prove that current is able to oppose each other and there are other ways to control it than the normal ones...

It maybe helpful to google "superposition circuits" as that is what this problem is...

V1 and V2 are only used to find "their" current through each resistor... more like... V1|V2 Total I2+I2=I2total (will be the ONLY one that adds) I3-I3=I3total I4-I4=I4total etc.. etc... with real numbers (V1I2) + (V2I2) 153.85mA+692.3mA = I2 total (V2I3) - (V1I3) 923.07mA-461.54mA = I3 total...

gneill's sketch kinda shows the current loop for V1 the left circle is should go clockwise...as current flows from the negative side.. basically the direction of current flow...and with V1 in the circuit and no V2... *edit start for V1 R4 R3 would have total current...your current would follow...

This is a pretty basic "super position" problem... basically solve it as if were a series parallel circuit... twice remove V2 and replace it as a "short" then solve for current through each resistor... then replace V2 and remove V1 replacing it as a short... Current flows from the...
