DetermineVfor the network in Fig. 7.24 (left-hand image)._{C}

2. Relevant equations

Kirchhoff's Voltage Law: The algebraic sum of the potential rises and drops around a closed path (or closed loop) is zero.

3. The attempt at a solution

This is an example problem in my book "Introductory Circuit Analysis" by Boylestad, 12th Ed., page 256. I understood KVL in the chapter on series dc circuits. There, closed loops were obvious.

My hangup with this question isI don't see how Fig. 7.25 represents a closed loop.

The book states:

[tex]V_{C}+V_{R_C}-V_{CC}=0[/tex]

Why are we subtractingV?_{CC}

Can somebody post a Microsoft Paint drawing to show me how Fig. 7.25 is a closed loop?
