In this interactive object, students work 11 practice problems and solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

Learners will understand how binary-coded decimal information is decoded and used to drive a seven-segment display.

In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this learning activity you'll determine the total resistance in a DC parallel circuit.

Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.

Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.

Students follow step-by-step directions on how to make mathematical calculations for a Wheatstone bridge.

In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.

Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
