In this interactive object, learners work 10 problems covering resistors, voltage, and current.
Voltage Source Approximations
By Patrick Hoppe
Students examine the first and second approximations of a voltage source. A "stiff" voltage source is defined, and several examples are given.
Methods of Producing Electricity
By Terry Bartelt
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
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.
The 7493 IC Binary Counter
In this interactive and animated object, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts. A quiz completes the activity.
DC/AC I: Unit 8 Sample Exam
Students answer five questions concerning magnetism.
DC/AC I: Unit 9 Sample Exam
In this interactive object, learners answer nine questions about inductors.
DC/AC I: Unit 10 Sample Exam
Learners answer eight questions about capacitors. Help pages are available.
DC/AC I: Unit 11 Sample Exam
Learners answer six questions about transformers.
DC/AC I: Unit 12 Sample Exam
A sample exam for DC/AC I, unit # 12 is presented to the students. This unit covers transformers.
