Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.

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.

Learners study the theory of operation for a ratio pyrometer that measures temperature. A short quiz completes the activity.

Instructors complete a simple, informal inventory that helps them to see how they use the Seven Principles of Good Practice in Undergraduate Education developed by Chickering and Gamson (supported by AAHE, ACE, Johnson and Lilly foundations) in 1987.

Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.

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 analyze a base-biased npn transistor circuit. A "help" screen is available.
