The College Board advises that students choosing AP English Language and Composition be interested in studying and writing various kinds of analytic or persuasive essays on non-fiction topics, while students choosing AP English Literature and Composition be interested in studying literature of various periods and mediums (fiction, poetry, drama ...
An electric circuit is an interconnection of electric components such that electric charge is made to flow along a closed path (a circuit), usually to perform some useful task. [ 56 ] The components in an electric circuit can take many forms, which can include elements such as resistors , capacitors , switches , transformers and electronics .
The Chief Reader's decision is based upon what percentage of students earned each AP Grade over the previous three years, how students did on multiple-choice questions that are used on the test from year to year, how he or she viewed the overall quality of the answers to the free response questions, how university students who took the exam as ...
Advanced Placement (AP) Physics B was a physics course administered by the College Board as part of its Advanced Placement program. It was equivalent to a year-long introductory university course covering Newtonian mechanics, electromagnetism, fluid mechanics, thermal physics, waves, optics, and modern physics.
Multiple choice questions lend themselves to the development of objective assessment items, but without author training, questions can be subjective in nature. Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
The ampere is an SI base unit and electric current is a base quantity in the International System of Quantities (ISQ). [4]: 15 Electric current is also known as amperage and is measured using a device called an ammeter. [2]: 788 Electric currents create magnetic fields, which are used in motors, generators, inductors, and transformers.
Before the 2024–25 school year, the multiple choice and free response section were each allotted 45 minutes, with 35 questions for the former and 3 questions for the latter. This made AP Physics C: Electricity and Magnetism, along with Mechanics, the shortest exams offered by the College Board.
Experiments involving triboelectricity and static electricity occurred before the discovery of the electron. The name ēlektron (ἤλεκτρον) is Greek for amber, [10] [11] which is connected to the recording of electrostatic charging by Thales of Miletus around 585 BCE, [12] and possibly others even earlier.
