In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.

Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.

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.

Learners examine the use of the tolerances displayed in a title block by calculating the minimum and maximum allowable size of a fabricated part. In a brief quiz, students determine whether a part is usable or should be scrapped.

Students answer five questions concerning magnetism.

In this interactive object, learners answer nine questions about inductors.

Learners answer eight questions about capacitors. Help pages are available.

Learners answer six questions about transformers.

A sample exam for DC/AC I, unit # 12 is presented to the students. This unit covers transformers.
