Students work five practice problems to determine the Thevenin resistance of DC circuits.
AC Voltage Conversions
By Terry Bartelt
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.
Excel: Complex Subtraction
By Patrick Hoppe
Students view the steps for subtracting complex numbers in Excel.
Series RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Fahrenheit/Celsius Temperature Scales
Learners study the process of mathematically converting temperatures between the Fahrenheit and Celsius scales. A short quiz completes the learning object.
Oscilloscope: DC Voltage Measurements
Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.
Total Impedance of a Parallel Circuit Using Complex Numbers
Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
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.
