[Phys-L] more about basic DC circuits



The last true/false quiz provoked an interesting discussion.

So let's take another step in that direction. I'll make it
really easy, by telling you where you can look up the answers.

Q3: True or false: Electrical current is conserved. This
means current cannot be "used up".
Knight, page 892 and page 896.

Q4: True or false: In a circuit, energy can be "used up".
Knight, page 896.
