Reading #2

Kirchoff's Laws/Ohms Law: This is classically Chapter 2 where these fundamental concepts are introduced and articulated in an engineering format. Try to keep clear the conservation law that are reflected in Kirchoff's Laws and the devices described by Ohm's Law and those that are not. Resistance always exists but it is not always subject to Ohm's Law.

What is resistance conceptually? What is the difference between resistance and resistivity?

How are v, i , and R related in general? What important distinction makes this into Ohm's Law?

What are the units of resistance? Is this a big unit or a little one?

What are open circuits and short circuits in an ideal world?

What are nodes, loops (meshes), and branches?

How do you determine if multiple devices are in series or in parallel?

Is it formally possible for two objects to be both in series and in parallel?

What is Kirchoff's node (or current) Law?

What conservation law does this reflect?

What is Kirchoff's Loop (or voltage) Law?

What conservation law does this reflect?

How do I use these to solve planar circuits?

How many of each equation to I expect to find in my system of equations?

What is a voltage divider? What is a current divider?

What is a Wye to Delta transformation? Why is this necessary?
