I'm trying to work out an equation for the circuit below,but unfortunately I'm not having success.I've managed to get the expression for I1 which is:


How do I find now the expression for I2?Following the equation V=RxI where V is the difference at both terminals of the resistance I need to find the value tension at point A.How do I find that value?I've found the parallel resistance between the resistances that correspond to currents I3 and I4 which is R by I don't know how to work it from that!
Any help is really appreciated!Thanks in advance!
