Learners view the operation of the 7485 integrated circuit magnitude comparator in this animated object. A quiz completes the activity.

Learners read an explanation of how to connect two 7485 ICs to compare binary numbers by creating an 8-bit comparator. Diagrams and charts are presented.

Students view the development of the transfer function for a RC high pass filter. They also read how a Bode plot is developed through simple approximation techniques for both the magnitude and phase.

Learners read how to convert complex numbers to their polar equivalent in Excel.

In this learning activity you'll place given vectors in correct positions on the Cartesian coordinate system.

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

In this animated and interactive object, the learner uses a Casio fx-260 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this animated and interactive object, the learner uses a TI-36X calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this learning activity you'll demonstrate the magnitude of Gross National Product.

Learners read a description of torque and study the factors that cause its magnitude to change.

Learners examine how a force may be considered to act at any point along its line of action as long as the magnitude and direction of the force remain unchanged. Numerical verification is provided.
