In this learning activity you'll review the hexadecimal numbering system.
Total Impedance of a Parallel Circuit Using Complex Numbers
By Patrick Hoppe
Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
By Barbara Anderegg
After a brief review, the student solves five practical shop problems using right angle trigonometry.
Indirect Measurement Instruments
By Kelly Curran
The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.
Phase Relationships Between Line-Neutral and Line-Line Voltages
By Michael Gradinjan, Terry Fleischman
Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.
Adding Fractions With Unlike Denominators
By Tina Dietzman
Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
Total Impedance of a Series Circuit Using Complex Numbers: Practice Problems
Students solve six problems for series impedance using complex numbers. Immediate feedback is given.
Total Impedance of a Parallel Circuit Using Complex Numbers: Practice Problems
Students work six practice problems to determine the total impedance of a parallel circuit.
