Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.

In this animated and interactive object, learners examine how changes in applied voltage affect the current and voltages in a zener diode voltage regulation circuit. A short assessment completes the activity.

Learners view practical examples of how a Hall-effect sensor is used.

Students view the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of an energizing RL circuit.

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.

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 above resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency is increased above resonance.

In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.
