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.
In this animated object, students view an explanation of how current, voltage, and the magnetic field strength of a series RL circuit change during five time constants. A brief quiz completes the activity.
Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-30XIIS Calculator)
Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.
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.
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.
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.
