In this learning activity you'll determine the total resistance in a DC parallel circuit.
By Patrick Hoppe
Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.
Capacitor/Inductor: An Auto Analogy
By Roger Brown
Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.
Truth Tables (Screencast)
By Terry Bartelt
Instructions on how to use and construct a truth table for digital devices are provided.
A Sample DC/AC I Exam
Students complete a sample exam for DC/AC I. It provides an overview of the material presented in the course.
Inductive Reactance Practice Problems
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
Parallel LC Circuit Tic-Tac-Toe 1
By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.
Parallel LC Circuit Tic-Tac-Toe 2
By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency is increased above resonance.
Vector Diagram for a Parallel RL Circuit
Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.
