Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.

Students view the steps for determining the total capacitance for a series circuit. They then work practice problems.

In this learning activity you'll review how an open in a series circuit affects current.

Learners examine first and second approximations and view examples of a "stiff" current source.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.

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.

In this animated object, learners identify the basic parts and operation of a crank slider mechanism. They also follow the steps to use rotational input velocity to determine the linear output velocity of a slider component.

Learners study the operation of the retro-reflective optical sensor, along with the guidelines that should be followed regarding the target size, reflector size, alignment, and the reflectivity of the target.
