In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.

Learners review Ohm's Law and then 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 learning activity you'll practice calculating the between the binary number system and the decimal number system.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

In this learning activity you'll review the process of solving for the total resistance in a series DC circuit.

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.

Students examine how to interpret resistor color code bands to determine resistance values and tolerance ranges. This interactive learning object has audio content and includes exercises.

In this learning activity you'll determine the total resistance in a DC parallel circuit.
