In this interactive object, learners solve additional problems involving total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

In this animated and interactive object, learners examine why the voltage produced by an AC drive must be increased when its frequency is increased due to inductive reactance.

In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.

Students read the vocabulary associated with frequency response as it relates to an amplifier.

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

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.

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 view animations and video clips showing how power is transmitted from one energized coil to another.

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

This game is designed to prepare you for your magnetism quiz.
