Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.

Learners examine the internal components of an optical encoder used in automated manufacturing applications. A brief quiz completes the animated activity.

Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.

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 by each resistor.

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 practice problems on voltage, current, and impedance matching. Examples precede the problems.

A sample exam for DC/AC I, unit # 12 is presented to the students. This unit covers transformers.

Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
