Discussion: current, voltage, and resistance.
Scientists often make predictions. To make a prediction, scientists use the best possible and most available prior knowledge that they have at the time. Sometimes the predictions are correct, and sometimes they are not. In this discussion, you will practice making predictions based on what you see when you quickly skim through a portion of the textbook.
Skim Ch. 20, "Electric Current, Resistance, and Ohm's Law," of College Physics in this week's Learning Activities folder. (You do not need to read this chapter in full to answer the discussion questions. You will read the chapter later this week as you complete your activities and assignments.) After you have skimmed the chapter, select 1 section (e.g., Section 20.4: Electric Power and Energy). Concepts related to Electric Current can help provide useful background while reviewing the chapter.
Respond to the following:
Identify the title of the section you selected.
Predict how the information in the section you selected might add to your understanding of the learning goal for this week: Use forces and fields to explain and quantify electricity.
Predict how information from the section you selected might help you in your future career. Also, discuss how not knowing the information might hinder your future career.
Pick 1 image, figure, or graph from the section that stands out to you and briefly describe it. Provide the figure number, a figure description, and the page number of the image (e.g., Figure 20.13, types of lightbulbs with different resistance, current, and energy, p. 872). Discuss what made the image interesting to you and why you selected it.
Students studying electricity concepts may also benefit from reviewing broader Physics topics and applications in Electrical Engineering.
