Students work practice problems to calculate the total resistance of a circuit. Feedback is provided.
The TI-86 Scientific Calculator: Using the Reciprocal Function for Complex Numbers
By Patrick Hoppe
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.
Learners read a description of inductors and view examples of inductors in series and in parallel.
Transistor Fundamentals: Collector Saturation and Collector-Emitter Cutoff
Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.
Statics - Trig: Pythagorean Theorem Calculations Using a TI-86
By Steve Whitmoyer
In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
Ohm's Law Practice Problems #1
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
How Adding Parallel Branches Decreases Total Resistance
By Terry Bartelt
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
Total Resistance in a Parallel Circuit
The learner will apply the three formulas used to find the total resistance of three types of parallel resistor circuit configurations.
