Learners view an animated demonstration of how to determine the final output of the combinational circuit.

In this animated object, learners examine how hydraulic jump affects drain flow and pneumatic pressures in the drain system.

In this learning activity you'll test your ability to select the proper gage blocks when making a stack.

Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.

Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.

Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.
