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

Learners examine how to convert numbers from rectangular to polar form and from polar to rectangular form using a TI-83 Plus calculator.

Learners review Ohm's Law and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

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.

Learners consider why an impedance matching transformer is needed to connect an antenna to a television.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.
