Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.

In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.

The learner examines the setup process of a TI-83 Plus calculator. The process is demonstrated and examples are given.

In this learning activity you'll apply the Pythagorean Theorem to isosceles and equilateral triangles.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

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.
