Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Learners view a vector diagram for a series RL circuit. Information on the voltage across each component, the total voltage, and the phase angle is included.

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 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.

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.

Transfer Functions: The RL High Pass Filter (Screencast)

Learners read how the RL high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.
