Students follow the steps for finding the total impedance for a series-parallel circuit. Several examples are given.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

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.

In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

Learners view two animations that show the effects of eddy currents.

In this learning activity you'll calculate the total inductance of a series circuit.
