Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
Automotive Electrical Systems: Effects of a Rheostat in a Series-Parallel Circuit.
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 read an extensive explanation of the types of budgets most frequently used by farm operators, whole farm, partial, and enterprise, and complete a brief quiz to test their knowledge. Farm financial standards and ratio calculations are provided. Exercises complete the activity.
In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.
Users calculate the tonnage required to punch holes in a specific base metal. The formula to be used is provided along with the tensile strength for various metals. A calculator is required.
The learner reads an explanation of how to determine lengths for tubing and pipe bending and then performs calculations in an interactive exercise. Two methods for determining angle bends are shown. A calculator is required.
In this interactive object, learners follow the steps required for the Ziegler-Nichols Continuous Cycling method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
Conversion Between Mass and Moles of an Element (Screencast)
Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.
Converting Between Standard and Metric Measurements
As a welder, you'll need to know how to convert between standard and metric measurements. Try this activity to practice converting between these two measurements. A conversion chart is provided to help you complete this work.
