In this interactive object, learners examine the PN sections of a diode and the diode's forward- and reverse-biased operations. A brief quiz completes the activity.

Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.

In this animated object, learners study the rotation of the magnetic stator field of an AC motor and how it interacts with the armature to cause rotation. A short quiz completes the activity.

Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.

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.

Learners view a vector diagram for a series RC circuit and read information concerning the voltage across each component, the total voltage, and the phase angle.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.
