In this learning activity you'll review methods for testing an on/off switch with an ohmmeter and a voltmeter.

Learners examine the animated Timer-On Delay instruction and the Timer-Off Delay instruction of a PLC timer. A brief quiz completes the activity.

The technique for designing a MOD 10 counter is introduced. Asynchronous inputs of a JK flip-flop are used to clear the counter.

In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.

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.

Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
