Lots More Circuits

C Block jumped into parallel circuits today and used their lab data to illustrate our discussion. In parallel circuits, the potential difference in each branch is the same, but the current through each branch is different. It is flip-flopped for series circuits, so make sure you are very clear which pattern corresponds to which circuit type. Adding more resistors to series circuits increases overall resistance, but it decreases equivalent resistance for parallel circuits. The problems you have for homework should help you work out the math bit and some of the items will give you practice contrasting properties of series and parallel circuits. We'll go over this tomorrow before starting our review for Wednesday's exam.

E Block reviewed the concept of combination circuits and then worked additional practice with that circuit type. F Block was introduced to combination circuits and is getting their first practice with them tonight for homework. We'll look over these tomorrow before starting our test review. The B and E Block exam has been postponed until Friday, but we will be starting with Magnetism in the meantime, so don't forget to to study on Thursday night! Today, B Block worked on their series and parallel circuits lab, which should have been a good opportunity to practice practice what you've already covered about those circuit types. We'll have a general review tomorrow and go over your combination circuit homework problem, so have those labs ready to hand in when you get to class.
