Does anyone know how to do question 3 from the 2006 paper? Or even where to find the information about how to do it? I've got part way through it if anyone wants to compare results, but I've hit a bit of a wall. A colleague and fellow candidate mentioned Kirchoff's laws & simultaneous equations which took me back to my uni days and I could feel my blood pressure rising. 
Is there a simple answer to this or do I really need to dig out my textbooks?
