Question 70 of 75
Calculate the total impedances (complete with phase angles) for each of the following capacitor-resistor circuits:
Reveal answer
Notes:Have your students explain how they solved for each impedance, step by step. You may find different approaches to solving the same problem(s), and your students will benefit from seeing the diversity of solution techniques.
-
Question 71 of 75
Complete the table of values for this circuit, representing all quantities in complex-number form (either polar or rectangular, your choice):
Reveal answer
Notes:Ask your students to share their problem-solving techniques for this question: how they solved for each parameter and in what order they performed the calculations.

Question 72 of 75
Determine the size of capacitor (in Farads) necessary to create a total current of 11.3 mA in this parallel RC circuit:
Reveal answerC = 562.2 nF
Notes:Have your students explain how they solved for each impedance, step by step. You may find different approaches to solving the same problem(s), and your students will benefit from seeing the diversity of solution techniques.
