My confusion for lecture three is how the current divider law works with more than two resistors in parallel, the opposite R value going in the numerator wouldn't make sense in these cases. Is it even possible to apply the law with more than two resistors?
What I do with more than 3 branches: to find the current in branch #1, I combine the resistors in the other branches. Then apply the current divider rule to find the current in branch #1 and the combined parallel resistance of the other branches that have been combined into one resistance.
Pierce - did the in-class work help with node counting? If not, I can help again in class on Friday - just please remind me to help. Or pop by my office. I have candy
Again there's no post for lecture comments!!

As stated in class, there is not an assigned blog.
