Hello from Oz

My basic understanding is that when you parallel resistors, the value is the larger minus the smaller. I have a design which needs a 4.7 ohm resistor as part of an L-Pad; I don't have a 4.7 ohm, but I have a 5.6 and a 1 ohm. So, if I'm right in my understanding, wiring the resistors in parallel should give me 4.6, close enough. But according to Xsim, it doesn't, at least in the FR graph, so can anyone see where I'm wrong please?

Of course, I'll buy the 4.7 ohm resistors, but I'd like to know where I'm wrong.

Thank you

Geoff
