Thanks for posting a question! These questions in the Voltage Drop quiz are important to understand.
To start with, look back at the quiz results for that unit. You’ll see the questions and the answers you gave, but now you will also see some “explanations” showing up for some of the questions. Look over those explanations and see if that helps you. If you still are having trouble figuring out the correct answers, then reply here with more detail on where you are getting lost, and I’ll continue to work with you on that.
Also, if there are any other things that were taught earlier in the Basic Electricity module that you didn’t quite get, you should work on those as well. All of this information we’re teaching in these units is connected and important for understanding how circuits work.
