In this circuit I1=0.08332 A, I2=0.18653 A, I3=-0.005 A How do i find I R4 and V R5?
According to the circuit, shown in the attached picture,
Current through `R_4` = Current through `R_3` + Current through `R_5`
So, `I_R_4` = 0.18153 A
Again, voltage through `R_5` =(current through `R_5` )*`R_5`
Thus, `V_R_5=-0.375 ` V.
Negative value of voltage means current flow will be in the opposite direction, which is indeed the case for R5.
