In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.
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.
The TI-83 Plus Calculator: Using the Reciprocal Function for Complex Numbers
Learners examine the correct method for calculating complex reciprocals. The solution for total impedance of a parallel circuit in rectangular form is shown.
Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.
Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.
In this animated activity, learners listen to instructions for simplifying a complex fraction by finding the least common denominator. This learning object requires a computer that is equipped with speakers.
Complex Power: The Sum of the Individual Real and Reactive Powers
The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.
