I'm confused with something really basic, and it is bothering me. I'm not sure if there is a way to draw circuits with LaTeX on this forum (or even how to do it if there is), so please excuse the ASCII art. (If there is a way to draw them, I'll be more than happy to learn. Anyways...
Lets say you have a circuit as such:
How do you know how to label the currents? The professor just throws in currents, and I don't understand why, or how he is doing it. Is there an algorithmic way to do it? I always seem to be adding more currents than what is necessary. If someone could just point me to a website, explain it, or give any insight I would appreciate it. I don't want to get far into this course and not understand it. Thanks.
Also another question. How do you know how to assign polarity to circuit elements.
ex)
Lets say you have a circuit as such:
Code:
R_1
----------\/\/\----------
| | |
| | \
(+) V_0 (-) V_1 / R_2
(-) (+) \
| | |
| | |
----------\/\/\----------
