In this interactive object, learners answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.

Learners view a sample of the keystrokes on a TI-36X calculator that are required to solve for the instantaneous current of an energizing RL circuit.

Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units. Practice problems are included.

In this teaching and learning aid, the user can 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.

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.

Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.

You'll practice solving problems using the rule for multiplying powers with the same base.
