This project gives a drawing with steps to complete the activity.

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.

In this animated lesson, students read an analogy comparing water in a "special" water tank to the current "flow" through a capacitor.

Students view a video that shows the correct methods for starting a GTAW weld pool and adding filler. It focuses on the two problems that many students have – adding filler too soon and angling the torch so that the filler melts prematurely on the filler rod. Note: This activity is 3.6 mb.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work six practice problems to determine the total impedance of a parallel circuit.

Students solve five problems to determine the total impedance of a series-parallel circuit. Immediate feedback is given.

This learning object describes the equipment and supplies needed to document bloodstain patterns.
