Hey guys, I'm just trying to get my head around the RGB tristimulus graph, as follows: http://cnx.org/content/m18092/latest/trist.png Why are there negative values for red? What does it mean? I'd appreciate it if someone could help. And no, this isn't a homework question, it's part of my...

No one can help?

Homework Statement Homework Equations KCL The Attempt at a Solution I recognise that the voltage sources form supernodes. This produces: A - B = 10 -> A = 10 + B We also know that node C is 12v. I then form KCL equations: 6 + \frac{A - C}{12} = \frac{B}{40} + \frac {A}{24} When I...

Look up 'supernodes'. Basically, the nodes on either end of the voltage source combine into a single node. If the nodes are, for example, A and B, and the voltage souce between them 12v, then: A - B = 12v (where A - B just means "the voltage difference between A and B") Since A and B are...
