In this animated object, learners examine the fundamental operation of a noninverting operational amplifier. A brief quiz completes the activity.

The learner will examine the basic characteristics of the operational amplifier integrated circuit and solve for Vout.

In this animated object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.

In this animated object, learners study what happens if the maximum switching speed of a proximity sensor is exceeded.

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 and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.
