Learners examine the two methods used by programmable logic controllers to perform a counting operation using addition or counter instructions. A brief quiz completes the activity.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.

Learners read the characteristics of the TTL series. Examples are given and subfamilies are compared.

Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.

Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.

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

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.

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.
