Students view the steps for dividing complex numbers in Excel.
Standard Transmission Signals
By Terry Bartelt
Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.
The Transfer Function and Frequency Response of a Low Pass Filter
By Patrick Hoppe
Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.
Time Proportioning Application
In this animated activity, students view the plastic pellets in a profile extrusion machine being melted as the temperature of the heating elements is elevated by a time proportioning control system.
Sine Wave Fundamentals: Practice Problem #9
In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.
Basic Terms in Division
By Barbara Laedtke
In this interactive object, the learner examines the basic terms used in division. A quiz completes the activity.
Effects of a Rheostat in a Series Circuit
In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.
In this learning activity you'll explore the operation of frequency division using several different types of counters.
The TI-86 Scientific Calculator: Using Complex Numbers
This primer introduces the student to the correct method of entering complex numbers into a TI-86 calculator.
The TI-86 Scientific Calculator: Using the Reciprocal Function for Complex Numbers
This primer introduces the student to the correct method of using complex reciprocals in a TI-86 calculator. The solution of total impedance of a parallel circuit in rectangular form is shown.
