AP Physics C: Electricity and Magnetism Practice Exam Walkthrough and Explanations | Charlie
10In this video I will give a detailed and thorough walkthrough of the 2017 practice exam of the AP Physics C: Electricity and Magnetism - calculus-based CollegeBoard course. I will explain each MCQ (multiple-choice) question in great detail and go over the steps involved in solving them.
About the AP Physics C: Electricity and Magnetism course:
Explore concepts such as electrostatics, conductors, capacitors and dielectrics, electric circuits, magnetic fields, and electromagnetism. You’ll do hands-on laboratory work and in-class activities to investigate phenomena and use calculus to solve problems.
Units:
Unit 1: Electrostatics
You’ll begin your study of the electric force with an exploration of electric charges.
Topics may include:
Coulomb’s Law
Electric field and electric potential
Electric potential due to point charges and uniform fields
Gauss’s Law
Fields and potentials of other charge distributions
Unit 2: Conductors, Capacitors, Dielectrics
You’ll explore how electric charge can move through an object and the factors that affect the way charge moves.
Topics may include:
Electrostatics with conductors
Capacitors
Dielectrics
Unit 3: Electric Circuits
You’ll build on your knowledge of electrical components to investigate the nature of electric circuits and explore current, resistance, and power.
Topics may include:
Current and resistance
Current, resistance, and power
Steady-state direct-current circuits with batteries and resistors only
Gauss’s Law
Unit 4: Magnetic Fields
You’ll begin your exploration of magnetism by learning how magnetic fields are generated, how they behave, and how they relate to electricity.
Topics may include:
Forces on moving charges in magnetic fields
Forces on current carrying wires in magnetic fields
Fields of long current carrying wires
The Biot-Savart Law and Ampère’s Law
Unit 5: Electromagnetism
You’ll build on what you’ve learned about charges, currents, and electric and magnetic fields to explore electromagnetic forces and their properties.
Topics may include:
Electromagnetic induction (including Faraday’s Law and Lenz’s Law)
Inductance (including LR circuits)
Maxwell’s equations
