Homework Statement
Determine VC for the network in Fig. 7.24 (left-hand image).
Homework Equations
Kirchhoff's Voltage Law: The algebraic sum of the potential rises and drops around a closed path (or closed loop) is zero.
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 is I 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 subtracting VCC?
Can somebody post a Microsoft Paint drawing to show me how Fig. 7.25 is a closed loop?
