## Homework Statement

Consider the circuit shown below.

(a) How many extraordinary nodes does it have?

(b) How many independent meshes does it have?

(c) The values of how many of those mesh currents can be determined immediately from the circuit?

(d) Apply mesh analysis to find I’.

## Homework Equations

## The Attempt at a Solution

I am having a hard time for parts (a) and (b). I put a dot on everything I called an extraordinary node, and got 5. My friend got 10 and I don't see it.

Also, the the independent meshes, apparently where the 7 Amp current source is, you can't say the furthest right branches mesh current by inspection. How is this?
