Ok so I'm pretty new to electronics. Taking a part time course one day a week and trying to fit it in with working 60 hours a week. My lecturer moves through things pretty quickly and the rest of the class have a background so I'd rather not hold them back with my pretty basic questions seeing as its a higher level course (don't ask how i managed to blag my way onto it).
So I'm stuck trying to calculate the current through I1 and I5 in this circuit, I've worked out the total resistance for the circuit and the total current, I just cant figure out how to calculate current through these points, its just not clicking for me.
