In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

Learners read about the benefits of storing raw materials within 3 feet of the work area where they will be used.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

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.
