What you need to know for AP Physics C: Electricity and Magnetism


Best AP Physics Coaching in New Jersey

There are two exams in the AP Physics C series: the first is called Electricity and Magnetism. If you want to start studying for this test, you've already completed and studied for the AP Physics C Mechanics exam. As you can see from the outline below, the appropriate study approach for this exam is extremely similar to the appropriate approach for the Mechanics exam because the forms are nearly identical. Reading on will provide tips on achieving the best score on the AP Physics C Electricity and Magnetism exam for both beginners and seasoned test takers.

Subjects Covered in the AP Physics C Test: Magnetism and Electricity

  • 30 percent is electrostatics.
  • 14% are made up of dielectrics, capacitors, and conductors.
  • Circuits for electricity: 20%
  • Magnetic Fields: 20%
  • 15% is Electromagnetism.

The exam includes every subject typically covered in an AP Physics C course on electricity and magnetism in high school, as you can see. Note that these subjects will not be evenly allocated across each segment of the test; rather, they will be covered throughout the whole test. Exam topics may include a single subject, like magnetic fields, in their separate multiple-choice and free-response portions. extremely heavy, and to make up for it, the other portion says nothing about it.

Specifically speaking, you should be aware that the exam's multiple choice and free response portions are designed to assess your knowledge of various applications of the content you have studied. A basic understanding of the course's ideas and formulas is tested in the multiple-choice part. Multiple-choice questions typically ask you to solve a simple problem using a formula or concept. This section's challenge is to retain the right formula and apply it correctly. Conversely, the free response portion assesses your capacity to apply ideas and formulas from many subjects to a given circumstance. You will always need to perform mathematical calculations and utilize a variety of formulas to adequately respond to a free-response question. Please don't worry if this is unclear. In the section that follows, we will review sample multiple-choice and free-response problems from the most recent AP Physics C: Electricity and Magnetism test. A more thorough comparison of the free response and multiple choice questions is provided below.

  • Questions with Multiple Choices
  • Evaluate the depth of the data
  • Simple inquiries: use a formula

Advantages: You should correctly answer the question if you are aware of the relevant formula.

Cons: There is no half credit offered, and you won't receive a formula sheet for this area.

Advice: Before beginning any section, make sure you have the pertinent formulas written down.

  • Unrestricted Answer Questions
  • assess the depth of the data

Extended questions: use your deductions as well as several formulas from various disciplines.

Benefits: Partial credit is awarded, and you will receive a formula sheet.

Drawback: Accurate application and derivation of formulas are required.

Guidance: Recognize the kinds of inquiries you might receive.

Reviewing every topic that will be tested should be your first step in studying. Go over the key concepts of each chapter and make a note of any significant formulas using your prep book and your class notes. You'll be ready to start working on physics if you complete a review. At this point, it's a good idea to print off the formula sheet you'll receive for the exam's free response portion so you can become acquainted with the data you'll need to pass.

Section C: Multiple Choice Questions on Electricity and Magnetism in AP Physics

Practice is essential to performing well on the multiple-choice portion of the AP Physics C Electricity and Magnetism test. It's that easy. This portion, as previously noted, assesses your fundamental understanding of every subject covered in the exam. Also, it measures your capacity to quickly respond to a wide range of questions on many subjects. You will need to be able to respond to each question fast and precisely since you will have 45 minutes to finish the 35 questions.

Practice questions for the exam are contained in your study guide. On past year's AP® exams, there are even more questions. Take as many of these as you can until you can do two or three tests in forty-five minutes, paying close attention to details. Furthermore, a formula sheet will not be provided for this portion of the test. You should thus study the formulae you will need to remember for the exam by using flashcards that include the formulas on the back and a pertinent AP issue on the front. You may get more details on how to make AP Physics flashcards here.

We will now review a sample multiple-choice AP Physics C Electricity and Magnetism issue from the course description booklet for AP Physics C.

On opposite sides of a cleared space between two sizable, parallel, charged plates, a proton and an electron are expelled simultaneously. The oppositely charged plate is the path that each particle is accelerated toward. Enough distance separates the particles to prevent them from influencing one another. Once at the plate with the opposite charge, which particle has the higher kinetic energy?

1) The electron
b) A proton
c) There is no particle; there is an equal kinetic energy for both.
d) Without knowledge of the potential difference between the plates, it is impossible to determine.
e) Without knowing the plate fee amount, it is impossible to determine.

While the question may appear to be a formula recall question, it is not. Because protons and electrons have the same charge, answers A and B are incorrect since kinetic energy is a function of charge rather than mass. The answers D and E are false because the charges of the particles are not different, which would be necessary for there to be a potential difference between the plates and the charge on the plates. As a result, C must be the response.
