PHYS 262 - General Physics II: Electricity and Magnetism
Coulomb’s Law, electric fields, Gauss’ Law, direct current and alternating current circuits, magnetic fields, the laws of Ampere and Faraday, and electromagnetic waves. Laboratory exercises also develop familiarity with electrical measuring instruments. PREREQUISITE(S): A grade of C or better in both MATH 182 and PHYS 161 and concurrent enrollment in MATH 280 or MATH 282 , or consent of department. Three hours lecture, three hours laboratory, one hour discussion each week Formerly PH 262.
4 semester hours
A calculus-based general physics course, required for students majoring in engineering or one of the physical sciences.
Upon course completion, a student will be able to:
- Solve mechanical and electrical oscillating system problems.
- Use Excel or a similar computational graphing tool to graph and fit curves.
- Find solutions to simple resistive DC circuits using KVL and KCL.
- Measure Hooke’s Law parameters for a mass-spring system and make comparisons to the electrical analogy for such in a system to AC circuits.
- Demonstrate understanding of Ohm’s Law for resistors, and also the constitutive defining relations for capacitors and inductors.
- Combine resistances and capacitances in series and parallel.
- Compute resistances, capacitances, and inductances for simple geometries and understand the effect of conductive, dielectric, and magnetic media for such geometries.
- Verify Ohm’s Law and Kirchoff’s Laws by using typical electrical measurement devices which measure currents, voltages, resistances, etc.
- Use Coulomb’s Law to calculate electric forces and electric fields due to point charges and continuous charge distributions.
- Use Gauss’s Law to calculate electric fields for highly symmetric continuous charge distributions.
- Demonstrate understanding of the fundamental operating principles of a Cathode Ray Tube.
- Use the Coulomb’s Law form of electric potential to compute the electric potential for point charges and continuous charge distributions.
- Compute the potential differences due to a given electric field.
- Solve simple problems involving electric energy and work.
- Demonstrate understanding of the field viewpoint versus the action-at-a-distance viewpoint of electric and magnetic forces.
- Apply Faraday’s Law and Lenz’s Law to problems with magnetic fields, both with constant and time-dependent magnetic flux.
- Solve simple DC-Circuit problems such as RC, RL, RLC circuits with various characteristics involving the “charging”, “discharging”, and “relaxation” of such circuits.
- Solve simple AC-Circuit problems involving characteristics such as impedances, resonance, power, phase, etc.
- Use the oscilloscope to measure time-varying voltages, frequencies, periods, amplitudes, phase, etc.
- Analyze and measure major circuit characteristics for RC, RL, RLC circuits driven by a square wave, and also sinusoidal AC-circuit configurations.
- Compute the magnetic forces on moving charges and wires.
- Use Biot-Savart Law to compute the magnetic field for simple current distributions.
- Use Ampere’s Law to solve simple problems computing the magnetic field.
