Ch. 18 Electric Currents 

Due Friday 20 January by 10 am


1. What is the function of a battery in a circuit?  (What does it do or why do we use one?)


2. Is current used up in a resistor?  What happens to current when a wire splits and goes to different parts of a circuit?


3. Are there any thoughts you wish to share, whether they are about this assignment, the reading (what seems impossible, what makes no sense, what you'd like to spend time on in class, what you really found interesting etc) or the course?
