I guess part of the problem has to do with how quickly my professor covered all the circuit chapters.
And I suspect the other problem is that I'm a visual learner. When I tackle the problem I usually close my eyes and imagine the equations and particles for a bit or draw a picture.
Well, there is a lot of things I don't understand.
1) How do these imaginary loops work. I'm talking of the ones you place arbitrarily in or around a circuit.
2) Sign Conventions
3) What is really going on within the circuits. For example, the resistors, emfs, potentials, loops, etc.
4) Why is that when you travel from a - to +, the emf is considered to be positive? And vice-versa?
Thanks, that helped a lot.
Oh, so the circuits introduced in the book have a lot of passive components? I never thought about it that way really.
Excuse my incompetence with circuits and resistors-- but what does it mean to go from a direction of high potential to low in a resistor? I thought resistors are just a part where things get slowed down a bit. What is going on within the resistor?
