In this learning activity you'll explore the operation of a full-wave bridge rectifier circuit.

In this learning activity you'll review the steps for determining the total capacitance of a parallel circuit and work practice problems.

Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.

In this learning activity you'll build a resistor's color code based on the bands.

In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

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