In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.

Learners view the steps for testing a capacitor with an analog ohmmeter. A brief quiz completes the object.

Learners review the VDR and work six problems. Immediate feedback is given.

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

A use of the CreateJS JavaScript Library to perform a looping animation.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work six practice problems to determine the total impedance of a parallel circuit.

Students solve five problems to determine the total impedance of a series-parallel circuit. Immediate feedback is given.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.
