This exam assesses course standards 32–37. If you can do the tasks described below, you will satisfy the standards on the exam.
State and name Maxwell's four equations (integral form).
State in plain language what each equation tells about electric and magnetic fields in space.
Given an electric or magnetic field magnitude, determine its energy density (energy per volume).
State and describe the voltage rule for inductors.
Name the unit of inductance, decompose it into other basic and derived SI units, and explain what the inductance tells about the behavior of an inductor.
Explain why certain components display inductance.
Relate the inductance of a component to its construction.
Identify the equivalent inductance of inductors connected in series and in parallel. Explain using the voltage rule for inductors and Kirchhoff's circuit rules.
Calculate the energy stored in an inductor.
Construct equations for the voltage across and current through the components in a charging or discharging RL circuit.
Identify the quantities determining the time constant of an RL circuit.
Calculate the time constant of an RL circuit.
Qualitatively describe and explain the behavior of an LC circuit.
Identify the quantities determining the angular frequency ω of an LC circuit.
Identify corresponding features of LC oscillators and simple harmonic oscillators.
Identify the relationship between primary and secondary windings and primary and secondary voltages in an AC transformer.
Qualitatively explain how a transformer produces a secondary emf. Identify the physical laws determining the properties (amplitude, frequency, phase) of the AC output.
