Solve the following problems on your own paper. Please:

• Show all work.
• Put a box around your final answer to each problem.
• Be sure proper significant figures (SF) used for all answers.
• Separate all solutions with a horizontal line on your paper.
• A random selection of four problems will be graded for 25 points each.
• Solutions for suggested odd problems can be seen by following links.
• Solutions for assigned problems will be linked from this page after the due date.

Chapter 18

#4

In part a, find the current first. In part b, find the voltage first.

#8

In part b, the total power can be calculated as if all the resistors were combined into a single equivalent resistor.

#14

You'll need to find the voltage and current in the entire equivalent resistor and then in each individual resistor in order to complete this problem.

#22a

Do only part a. This one is similar to #14.

#32

Answer each part with 3 SF.

#36

Find the resistance first from the information given in the problem.

#38

Answer each part with 2 SF.

#40

You can calculate the current either by arranging the resistors in series or paralle, but there is also an easier way to do this problem. Either way, you should get the same answer.

#54

We'll go through examples of this kind of algebra in class. Answer with 2 SF.
