This learning activity describes the abilities of an inductor coil to oppose alternating current and to pass direct current.

Learners examine the process for determining the total inductance of a parallel circuit. They then complete practice problems.

In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

Learners read a description of inductors and view examples of inductors in series and in parallel.

Students complete 10 practice problems.

This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.

This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.

Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

In this learning activity you'll calculate the total inductance of a series circuit.

In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
