Learners review Ohm's Law and 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.

Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.

Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.

Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. 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 interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.

Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.

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.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.

In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.

Learners read a description of the function of the coupling switch on an oscilloscope and how its setting affects measurements of DC, AC, and combined voltages. A brief quiz completes the activity.
