Learners view colorful animations showing the operation of a VR stepper motor.

In this interactive object, students work parallel circuit analysis problems. They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

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.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.

In this learning activity you'll practice converting from one metric unit to another.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.
