Students view the steps for determining the total capacitance for a series circuit. They then work practice problems.

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 examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.

Students read step-by-step instructions for determining the square root of a number using the TI-86 calculator.

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

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.
