In this interactive object, learners solve for the current through each resistor, the voltage across each resistor, and the power dissipated.
In this interactive object, learners work 11 problems covering atomic structure, conductors, and insulators.
Learners study the process of mathematically converting temperatures between the Fahrenheit and Celsius scales. A short quiz completes the learning object.
Learners solve word problems involving basic mechanical principles such as torque, horsepower, work, and power. Students who have problems with a particular word problem may try it again with a different set of numbers.
Learners view a horizontal curve and mouse over the diagram to read descriptions of its components and related equations.
Learners examine how to convert numbers from rectangular to polar form and from polar to rectangular form using a TI-83 Plus calculator.
This primer introduces the student to the correct method of entering complex numbers in both rectangular and polar form.
In this interactive learning object, students calculate a resultant of multiple forces acting in a concurrent, coplanar condition.
This animated lesson shows the operation of timer-on and timer-off delay relays used in ladder circuit operate.
This animated lesson shows how pushing a start or stop button on a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.
The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.
Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.
In this animated object, learners examine the operation of a Schmitt Trigger IC and its hysteresis function. A brief quiz completes the activity.
Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.
Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.
