(2 of 2) Electricity and Magnetism - Review of All Topics - AP Physics C

The video tutorial covers various physics concepts related to electricity and magnetism. It begins with the correct placement of voltmeters in circuits and the importance of resistance. It then delves into magnetic forces, the right hand rule, and torque on loops in magnetic fields. The Biot-Savart Law and solenoid fields are explained, followed by magnetic forces between parallel wires. Gauss's Law and magnetic flux are discussed, along with Faraday's and Lenz's Laws. The tutorial also covers motional EMF, inductance, RL circuits, and energy storage, concluding with LC circuits and simple harmonic motion.

Why should a voltmeter have high resistance?

• To decrease the circuit's resistance

• To allow maximum current flow

• To increase the circuit's voltage

• To minimize changes to the circuit

What does the right-hand rule help determine?

• The direction of electric current
