Flashcards: Understanding Resistors
Resistors are one of the most important basic components of a circuit. With very few exceptions, all circuits have at least one kind of resistor component. An ammeter is a device that measures current flowing through a circuit. Ammeters are always connected to a circuit in series.
Which of the following accurately explains why ammeters must be connected in series within a circuit, and never in parallel?
An ammeter connected in parallel would give readings of half the current flowing through the circuit because current would flow evenly between the ammeter and the circuit's regular pathway
An ammeter connected in parallel would not read any current because the current would have no driving force through the ammeter
An ammeter connected in parallel would give high readings of current because the current would be flowing through both the regular current path and the ammeter, but disproportionately through the ammeter
An ammeter connected in parallel would give very low readings of current because current would be flowing through both the regular current path and the ammeter, but disproportionately through the regular path
An ammeter connected in parallel would give the current flowing through the circuit a pathway with minimal resistance, creating a very large current that could harm the ammeter
All AP Physics C Electricity Resources
Our AP Physics C: Electricity flashcards each contain one question that might appear on the AP Physics C: Electricity exam. You can use them to get a comprehensive overview of each topic covered on the AP Physics C: Electricity exam one problem at a time, or to do problem drills that focus on particular problem types or content areas found on the AP Physics C: Electricity exam.
AP Physics C is a college-level course that is offered to high school students as an option for receiving college credit towards a degree in physics or engineering. AP Physics C: Electricity and Magnetism covers the specific field of electromagnetism and, along with AP Physics C: Mechanics, provides the foundation for important principles taught in other college physics courses. An AP Physics C course may cover curriculum from both the Mechanics and Electricity sections, though each exam is administered individually. The AP Physics C: Electricity and Magnetism exam is a timed test, and you will have 90 minutes to finish. With less than a minute to answer each question, it is imperative to be as prepared as possible prior to taking the exam. If you are searching for online study aids to help you review for AP Physics C, you’ll find a multitude of resources with Varsity Tutors’ Learning Tools, including AP Physics C: Electricity and Magnetism flashcards.
AP Physics C: Electricity and Magnetism covers a number of important topics, and you’ll find hundreds of flashcards containing all of the material you’ll need to review for your exam. Immediate feedback after each question helps reinforce relevant concepts. The free online flashcards are arranged by category so you can easily concentrate on the areas that need the most practice. Topics you can review include electric circuits, magnetic fields, capacitors, conductors, and many more. You can repeat each set of flashcards until you are fully confident on all of the material, and you can even add individual questions for further review to your own deck of online flashcards. You can utilize the free flashcards builder to add specific questions and narrow the focus of your studies even further. This helpful feature enables you to study more effectively, making better use of your study time.
One of the benefits of Learning Tools is convenient access to a variety of helpful online study resources. In addition to AP Physics C: Electricity and Magnetism flashcards, you can take advantage of numerous resources to study anywhere Internet is available. There are many AP Physics C practice tests that allow you to review certain topics with questions similar to those you’ll see on the AP Physics C exam. You can take each test as many times as you need until you feel comfortable with the material and ready to tackle the next subject. You can even use the online template to develop your own practice test using the questions that are the most pertinent to your learning objectives. A feature known as Question of the Day provides a pop quiz question on a different topic each day to help keep the material fresh and test your knowledge at random. Learn by Concept is another available tool, and you’ll find easy access to an interactive syllabus and even more sample questions.
