NOTE: These are the standard Sound & Communications textbooks/workbooks used for this course. Although one or more may not be within 5 years of the required published date, they are the most current books used when teaching this course. We will adopt the next edition of each text, as it is published.

## Types and/or Examples of Required Reading, Writing, and Outside of Class Assignments

A. Reading assignments:

1. Read DC Theory pp. 42-45: Electrical Properties of Materials

2. Read AC Theory pp. 29-33: AC Sine Wave Measurements regarding Peak-to-Peak, Root Mean Square, and Average Value

B. Writing assignments:

1. Explain in your own words how the number of electrons in the valence ring affects how materials conduct electricity. Provide examples

2. You will find that most equipment and voltage ratings are based using the Root Mean Square (RMS) values. Describe in your own words how RMS compares to a DC voltage and why it is typically used for voltage values
