AP Physics C: Electricity and Magnetism

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

AP Physics C: Electricity and Magnetism (Also commonly referred to as AP Physics C: E&M, or simply E&M) is an Advanced Placement science course about electricity and magnetism. It is one of the four AP Physics courses offered in some U.S. secondary schools.

Course content[edit]

It is supposed to be equivalent to an introductory college course in electricity and magnetism for physics or engineering majors.[1] The course modules are:[1]

  • Electrostatics
  • Conductors, capacitors, and dielectrics
  • Electric circuits
  • Magnetic fields
  • Electromagnetism.

Methods of calculus are used wherever appropriate in formulating physical principles and in applying them to physical problems. Therefore, students should have completed or be concurrently enrolled in a calculus class.[1]

This course may be combined with AP Physics C: Mechanics to make a unified Physics C course that prepares for both exams. In this scenario, Electricity and Magnetism is typically taught second, as it requires much of the knowledge gained in the Mechanics course.

AP test[edit]

The course culminates in an optional exam for which high-performing students may receive some credit towards their college coursework, depending on which college or university they attend.[2]

Registration[edit]

The AP examination for AP Physics C: Electricity and Magnetism is separate from the AP examination for AP Physics C: Mechanics. Before 2006, test-takers paid only once and were given the choice of taking either one or two parts of the Physics C test.

Format[edit]

The exam is configured in two categories: a 35-question multiple choice section and a 3-question free response section.[1] Test takers are allowed to use an approved calculator during the entire exam.[3] The test is weighted such that each section is worth half of the final score.[1] This and AP Physics C: Mechanics are the shortest AP exams, with total testing time of 90 minutes.[1]

The topics covered by the exam are as follows:[4]

Topic Percent
Electrostatics 30%
Conductors, insulators, capacitors, dielectrics 14%
Electric circuits 20%
Magnetic fields 20%
Electromagnetism 16%

Grade distribution[edit]

The grade distributions for the Physics C: Electricity and Magnetism scores since 2010 were:
